Accelerator not as responsive at times.

Intermittenly while driving my accelerator doesn't respond as sensitively. I have had this problem since 6 months after I bought it. The only light that comes on is the battery light for a split second as I turn the key over to turn the car off. I have had stall outs as the car is heating up from a cold engine and the battery light comes on when it stalls. It usually stalls when I start driving the car. When it stalls I am able to start it right back up no problem. Chrysler replaced the battery but it made no difference except instead of stalling my car stumbles around as it is warming up
Experienced mechanics share their insights in answering this question :
Hello. This may be a sign of a failing throttle position sensor. The throttle position sensor (TPS) is a sensor used to monitor the throttle position of the throttle plate inside the throttle body in relation to your foot position on the gas pedal.

The sensor is usually located on the throttle plate so that it can directly monitor the position of the throttle. The ECU then makes the direction to supply more or less fuel to the motor. When this sensor is not working properly, this can cause intermittent responses when pressing the gas pedal. If you want to have this work done outside of the dealer, a certified technician from YourMechanic can come to your home or office to inspect the acceleration issue and replace the accelerator pedal sensor as necessary.

How to Identify and Fix Common car Problems ?

There are a few reasons why your car might hesitate when you press the gas pedal. It could be due to a problem with the mass air flow sensor, the oxygen sensor, the TPS, or the fuel filter. It could also be due to a clogged or dirty air filter.
The most common cause of poor engine airflow is a clogged or damaged air filter. The air filter in your car protects the engine by catching all kinds of debris before it can enter the cylinder and cause more damage.
If your car is not accelerating, the first thing to check is the air filter. The air provided to the engine for the combustion process passes through an air filter, which catches all the impurities and debris present in the air. With continuous usage, the air filter gets clogged and doesn`t let air pass through it.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Fuel lines, dirty air filters, and throttle body issues can all cause a delayed throttle response. You can avoid this issues by installing a Throttle Response Controller. Engine response time will be improved, and you`ll enjoy driving your car more.
This hesitation while accelerating can be the result of a number of issues, including something like a clogged fuel filter or even a broken fuel pump. Sometimes, something could also be wrong with the transmission.
To recalibrate the ECM and accelerator pedal, the ignition switch must be in the ON position and then the accelerator pedal must be slowly and fully depressed from idle to full throttle. Repeat the procedure three times.
Accelerator Pedal Release Position Learning Procedure.

Make sure that the accelerator pedal is fully released. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds.

Easy ways to get ride of throttle delay is by making sure you keep up with basic maintenance like change fluids, air filter, fuel filter, tire pressure which all help to improve speed, fuel economy. Making sure you have clean fuel filter will help improve fuel economy, speed, and rpm at various shift points.
Control and adjust your throttle sensitivity easily with a throttle response controller. The fastest way to control your gas pedal response is by installing a device called a throttle response controller.
One of the most common causes for a rough idle and poor acceleration is a dirty or bad throttle body.
A number of possibilities can include low fluid levels, dirty transmission fluid, or a clogged filter.
Wondering why your car feels sluggish when accelerating? It could be due to a dirty air filter, a bad spark plug, or a faulty catalytic converter — among several potential suspects behind sluggish acceleration.
Typically when the car will not accelerate past 60 MPH, it`s due to either the ECU activating a limp mode or other mechanical (fuel or ignition system component) failures.
A malfunctioning TPS will cause your engine to run poorly. Generally the engine will idle fine but will have difficulty accelerating.
The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
“Limp Mode” – If your car won`t accelerate over 25 or 40 mph, it could have engaged `limp mode. ` It is also known as a limp home mode, and it acts as a preservation feature. It is meant to get you home, to an auto mechanic, or safely off the road without destroying your engine.
Do you have to reset computer after replacing throttle position sensor? After replacing the throttle position sensor in your engine, if the engine light was on and has a pending code, the code should go away. If the code doesn`t, however, then the ECM (engine computer module) will need resetting.
A turbocharger brings more air into the cylinders to produce more heat for better fuel combustion. It makes the engine more responsive and roll [faster], improving the torque. Turbochargers are also responsible for boosting the engine horsepower, which is also essential to increase the torque.
The easiest way to remove lag is by installing a device on your gas pedal called a throttle response controller. Throttle Response Controllers are blue tooth controlled, inexpensive, and make a big difference in immediate gas pedal response.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Accelerometer sensors have the ability to alter obtained physical acceleration from motion or gravity into a voltage output. Accelerometers are widely used to measure inert acceleration due to gravity, the low-frequency module of the acceleration and the dynamic acceleration due to animal movement [36].

At times my jeep will start fine and at times I have a hard time getting it to start. It seems like the wireless ignition node is
ANSWER : The recommended diagnostic to resolve this is a hard starting diagnostic. The work is performed by a certified mechanic right at your location. Among the first things the mechanic will check is whether required maintenance is up to date because old spark plugs, clogged fuel and air filters, and the like are potential causes of the hard starting you are describing. Other possible causes include a failing coolant temperature sensor, or bad connection to the sensor, problems with other sensors such as the cam and crankshaft position sensors, a defective fuel pump, and many other causes, all of which will be familiar to YourMechanic’s experts. With regard to the fuel pump, if the engine is not getting enough fuel it will be hard to start. If you request a hard starting diagnostic, YourMechanic will get this issue diagnosed and resolved for you.

need a way to retain the timing chain
ANSWER : The best way to approach this unfortunately is by using a timing chain tool retainer/holder tool. You may consider having an expert from YourMechanic come to your home replace the timing chain.

Timing chain positioning
ANSWER : This system is a bit complex. I can give you some instructions, but I highly recommend getting a hold of a repair manual or purchasing a yearly subscription for just your vehicle from AllData. It is only $25 for a years subscription from AllData.

There are two separate sets of marks on this system. One set is for aligning the timing chain to the camshaft gears and the intermediate shaft gear. There will be marks on the chain that raps around the crankshaft gear as well. These marks will not line up after you turn the motor over.The other marks are on the inside of the camshaft gears and align with the cylinder head parting line. If you were to draw a ling through the center of both camshaft gears, they should line up with that imaginary line.

The crankshaft key way should be aligned with the mating face of the main bearing cap. You can confirm it is in the correct position by verifying the number one piston is at top dead center. If you have removed the balance shaft timing chain, these marks really need a visual diagram to understand where they should be aligned. Without a diagram I am not very confident it can be explained very clearly.

This may be difficult to to follow, so again I highly recommend purchasing a repair manual in digital form or a book. If you feel this is over your head, I recommend the following inspection to help you out. Timing chain replacement

Good luck! I hope I was able to help you.

Sometimes my pickup accelerates supergood, other times it accelerates slow, at high RPMs.
ANSWER : This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

1992 Acura Legend, when the timing belt goes, is it common for the valves to bend?
ANSWER : If the timing belt break off, the engine’s pistons will hit the valves as the pistons are moving. The engine is an interference engine and can cause damage to the internals of the engine. The last time the belt came off, the engine may have been running at an idle or not under power. It is possible for the valves to be bent. What I recommend doing is performing a leak down test on the engine with a timing belt on the engine and properly timed to determine if the valves were in fact bent. If all of the cylinders have a 80 percent hold and not leaking, then the engine is fine. If there is a mass leak on a cylinder, then the piston did some internal damage. I recommend seeking out a professional, such as one from Your Mechanic, to help you check your engine’s valve train with a leak down tester.

Billing and parts question was sent to CS for the cost of parts and labor for valve train and related parts from a broken timing belt for a 1992 Acura Legend with a V6-3.2L engine.

Car hesitates and slows down badly at times. It almost stalls at times. It keeps slow speed at 20-30KM.
ANSWER : Hello. I would need to know the year of the vehicle to know where the fuel filter is located. If this is an older model, it is located under the vehicle. Most of the newer models only have a filter on the fuel pump.

From what you are explaining, it sounds like the fuel pump is failing. When the fuel is low, the pump will get hot and a weak pump will lose pressure causing this to occur. I would usually check the fuel pressure to see if it is low, especially when the fuel level is low. If it is, then the pump needs to be replaced. If you plan on having this done, consider YourMechanic, as a certified technician can come to your home or office to diagnose the hesitation problem and guide you with repairs.

My car twice out of 4 times today would not start on the first time. Second time started fine. At 2 read lights it was sort of je
ANSWER : Hello, thank you for writing in. Your symptoms point towards an issue with fuel or spark. If you just had work done on the fuel system, you may wan to have your fuel pressure tested at the engine. This will let you know that the lines, filter, and pump are all working correctly. You should also have the ignition system tested. This would mean inspecting the spark plugs to make sure they are in good condition, and making sure the plugs are receiving spark. Testing for spark is best done with a simple spark tester that is inserted into the plug’s wire. If having trouble starting, turn the key to the "On" position before starting, and let it sit. This give the fuel pump a moment to prime. If you do not hear the faint buzzing of the fuel pump priming (you may have to listen closer to the fuel tank), then you may be having issues with the pump. Only further testing will tell. For more help with testing and repairs, contact our service department to schedule an appointment.
