My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello, thanks for writing in about your 2002 Chevrolet Camaro. There are several things that can cause a backfire. Spark plug wires in the wrong location, a faulty fuel injector, a failing sensor and more. It looks like you already made a couple of adjustments to the car. You will want to double check and make sure those replacements were done correctly. If you would like to have another mechanic take a look at this, a certified technician from YourMechanic can come to your car’s location to diagnose the stalling issue and pinpoint the needed repairs.

How to Identify and Fix Common car Problems ?

A faulty or dirty mass air flow sensor may also cause the vehicle to produce a strong fuel odor when it is not functioning properly. The mass air flow sensor monitors air intake as it is mixed with fuel prior to being injected into the motor.
The Mass Airflow Sensor (MAF) measures the amount of air the car needs to accelerate. Once it gets that measurement it sends this information to the ECU which notifies the throttle to open accordingly. If the MAF is faulty and not measuring the airflow properly then you could experience a serious loss in power.
A bad MAF sensor can cause your vehicle to experience poor drivability issues such as engine stalling, jerking or hesitation during acceleration. This could happen while speeding up on the highway on-ramp or cruising down a city street.
Damaged O2 Sensor

This could also cause the exhaust to smell like sulfur or rotten eggs, so the presence of this smell alone isn`t enough to determine what the underlying problem is. However, it could also cause the exhaust to smell like gasoline.

Another common occurrence after the replacement of a faulty MAF sensor is the vehicle not idling correctly or a flat spot on acceleration, leading to the sensor being incorrectly blamed again. It is not uncommon for an engine to run a little rough and not idle properly initially after replacement.
Contamination is a key reason why MAF sensors fail and require replacement. As air, dirt and other debris get into the sensor, the parts become contaminated and fail. Drivers often notice sluggish performance, rough idling, poor acceleration or even stalling. There may also be a more frequent need to refuel.
the maf helps determine a/f ratios in typical driving so it has nothing to do with smell. the only instance where it might lead to a scent is if it goes foul and it makes the car run really rich and dump alot of fuel. if you are smelling a foul smell then you may have a clogged catalytic converter.
If you smell gas through your air vents, then your engine is burning too much gas which increases the amount of gas fumes coming out of your exhaust. This problem could indicate that you have a failing fuel pressure regulator. Here are the other symptoms to look out for: Black exhaust smoke.

Stalling, jerking, or hesitation during acceleration

A bad MAF sensor can cause too much fuel to be left in the combustion chamber, creating untimed detonations. You`ll experience this as poor drivability such as hesitations or sudden jerking motions, particularly during acceleration.

The smell of gasoline is usually an indication of a fuel leak. When you turn on the air conditioner or heater, the fumes, along with the smell, are sucked up and blown right into the cabin of the vehicle. As with exhaust fumes, the inhalation of gas fumes can be hazardous.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car crash and SRS light
ANSWER : Hey there. It is likely that your front impact sensor was damaged during the frontal collision but not with enough force to deploy the air bags. There is a threshold for how hard a vehicle must be hit in order to deploy the airbags that is set by the manufacturer that may not have been met. When the SRS light is illuminated, this means that the air bags will not deploy in the event of an accident, even if it is hit hard enough. I would recommend having the frontal collision sensor inspected and replaced if necessary by the dealer or a professional who is proficient in air bag repair.

Car intermittently won’t start
ANSWER : Hi there. An intermittent no start condition, can be difficult to diagnose. Replacing the fuel filter would not hurt anything, especially if it hasn’t been replaced in the last 30,000 miles. Diagnostic procedures should be performed, at the time of no start, to confirm whether there is a loss of fuel, of spark or both.

Assuming the Check Engine Light is not coming on, leads me to believe the ECM (engine control module)/computer is not recognizing the fault. There are many possibilities for a no start condition: a faulty ignition switch, fuel pump relay, fuel pump, ignition coil, ignition module, crankshaft position sensor, camshaft position sensor.

Replacing components without diagnoses can be expensive and time consuming without resolution. I recommend having your vehicle’s intermittent no start diagnosed and repaired by a certified technician, such as one from YourMechanic, so that this can be repaired correctly.

Do you think clutch can burn out within a year of the car being manufactured? How could this happen? Thank you.
ANSWER : Hi There,
8,000 miles on a burnt clutch is certainly a premature failure of the clutch. While there are many reasons this may have happened, getting Audi to warranty this may be a different battle and will be something you would need to address with the Audi dealership. Typically, the clutch slipping occurs when the clutch is in between fully depressed or fully released that bears the most wear. Many people do this without realizing it. Many people also unintentionally use the clutch pedal as a place to rest their foot when driving, however so slight, this will still cause the clutch to slip slightly causing it to burn prematurely. If you would like a second opinion on the condition of your clutch, you may wish to schedule an appointment with one of our qualified experts here at YourMechanic.
