Experienced mechanics share their insights in answering this question :
With a twenty five year old car, it really could be anything. So you have to start with the basics. The air filter was a good beginning, but other maintenance items like the fuel filter, spark plugs and ignition wires are all suspect. Also, your car uses a timing belt that has to be changed periodically or you run the risk of having the belt jump a few notches or even break. This can do serious damage to your engine. Since your car does not have advanced self-diagnostic capability, It’s not likely that anyone will be able to point at any one part and say "this is your problem" but you can get a good assessment by contacting Your Mechanic. They can send a technician to your home or office to check out your Maxima and let you know what steps you need to take to fix it.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
Common reasons for this to happen:
Loose connections at the positive and negative battery terminals. Very dirty or clogged air filters can also cause your engine to underperform. Loose timing belts are another likely cause. A mechanic will check these and replace them if they appear loose and worn.
Here are the possible causes of acceleration problems in Nissan Maximas: Failing or dirty mass airflow sensor. Clogged catalytic converter. Clogged air filter.
Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.
The source of the problem could be from tires that are not balanced or a worn-out spark plug. It could also be loose lug nuts. A car also vibrates for a number of reasons when you accelerate. Typically it`s from a damaged inner CV joint.
The most likely cause of the shuddering most often happens in the vicinity of your car`s rims and tires. They plant your car to the road, and if anything is broken, will feel it. On a serious note, it may be a broken transmission mount or a broken caliper.
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.
There are several causes for your car to lose power significantly while accelerating. The most typical causes of a car not accelerating while driving include a faulty sensor, contaminated fuel or air filters, or a faulty timing belt. Generally, this isn`t something you should ignore.

The air filter was a good beginning, but other maintenance items like the fuel filter, spark plugs and ignition wires are all suspect.

Car vibrate when in "D" or "R" although I have changed the 4 engine mounts. Changed 4 sparks and air filter and throttle cleanse
ANSWER : It seems you have covered the basics and changed the most common culprits for engine vibrations. I will recommend you have an experienced technician inspect the work done and the drivetrain for other problems. In some cases, an improperly installed new engine mount can cause a vibration to stay. Hire one of our experts here at Your Mechanic to inspect the previous work done and diagnose the source of the vibrations.
I unknowingly drove my car for the last 5,000 miles without an air filter, what potential damage has been done?
ANSWER : I do believe that no serious damage would have occurred. The air filter is made to prevent any leaves or other debris from entering the engine. However, due to the design of many newer intake systems, the debris would likely not make it that far anyway. This is due to screens that are built into some throttle bodies. I would recommend going with the intake/fuel system cleaning as well as another oil change. Once all of these maintenance items are completed, the vehicle should be good to go with no damage to worry about. If you want to have this looked at, a certified professional from YourMechanic can come to your car’s location to conduct a comprehensive inspection so that any issues can be addressed as needed.
I have a loss of power when acceleration the car does not drive pass 10 or 15mph I change the plugs and also change the fuel filte
ANSWER : This may be result of a failing or dirty mass airflow sensor. This is a unit that is responsible for regulating the air flow into the engine as it is mixed with fuel prior to being injected into the motor. When this is not working properly, this will cause an imbalanced air/fuel mixture resulting in a stalling or surging in the vehicle’s performance. The knocking sound may also be a result of the struggling acceleration which is common when the engine struggles to develop power. I would suggest having an expert from YourMechanic come to your home to take a look at your vehicle, and possibly replace your mass airflow sensor at your earliest convenience.
my car is hesitant to accelerate when changing down to second gear uphill and sometimes it just won’t accelerate.
ANSWER : Hi there. What were the diagnostic results? What were the data readings from the ECM? What diagnostic process did you use to determine the other parts were in need of replacement? These are the questions that I ask anytime I am presented with a unique concern such as this one. Compare data reading to factory specs before replacing any parts; air flow meters can be presenting incorrect readings that are not considered faulty readings. The ECM will simply adjust fuel trim to compensate. Of course, the meter may not be changing the reading at all from idle; imagine how the ECM will react to increased throttle opening with an airflow reading that matches idle speed (lots of throttle and no air) or increased airflow without an increase in throttle position if the TPS is faulty (lots of air and no throttle). I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car has low power inspection.
I have a2006 350Z convertible. The air conditioner doesn’t start until I’ve had the car running for at least 3 miles. I’ve tried t
ANSWER : Depending on how hot it is outside and how hot the interior of your vehicle is, it may take as long as 5 minutes on some vehicles to get the interior cooled down. The hotter it is inside the car the more difficult it will be to cool that space. I would recommend letting all the windows down for the first couple minutes of driving and then try the air conditioner. The cold air may begin coming out much more quickly this way.
Vehicle vibrates while accelerating and stops when you take your leg off the pedal or accelerate more
ANSWER : I suspect you have a problem in a CV joint, or if you have the all wheel drive version; in a drive shaft. The joints that enable the shafts to move around can wear out and when they do, they can produce a vibration at "resonate" speeds. There might be a vibration at 40 MPH that smooths out at 50 and then returns at 60. Or any other odd sounding pattern. You can have that conveniently checked out by contacting Your Mechanic. They can send a technician to your home or office who can check out your Toyota’s vibration and give you a more exact idea of what is the problem and what it will take to fix it.
Intake air flow leaking. What makes this happen?
ANSWER : Hi there. When having the code P0171, the fuel system is too lean. This could be the fuel pump is not working, the fuel filter is dirty or plugged, or the injectors are plugged or not working properly. Check the fuel system and make sure that the fuel system is having a pressure of 35 psi or higher. Also, check the spark plugs and look for any burn marks. This would indicate that the spark is hotter than normal and the fuel system needs cleaned or repaired.
For the intake air flow leak, check the intake for any vacuum leaks on both sides of the throttle. Check all of the hoses from the air cleaner box to the throttle and check the manifold and all vacuum line including the brake booster line for any leaks. Put a vacuum hose on the engine and see what the engine vacuum is at idle. The vacuum should be 17 hg to 22 hg on the gauge. If there is a vacuum less that that, then there is a leak. If you need further assistance with your fuel system and a vacuum leak, then seek out a professional, such as one from Your Mechanic, to help you.
