Inasmuch as you are writing in about uncommanded (aka, "unintended") acceleration, I can tell you the National Highway Traffic Safety Administration, one of the Federal agencies that tracks vehicle defects, would love to hear from you. You can file an...

Hi. Shifting problems on modern automatic vehicles usually lead to a failing solenoid. If it's a manual, it's more likely a mechanical problem either in the linkage or internal trans parts. I suggest having a mechanic from YourMechanic inspect your...

I would recommend replace the starter first since there are issues with it and a bench test only checks to see if it turns and does not test the drive gear. Replace starter and go from there.

Hi There, A number of things may cause the motor no to start. Depending on whether or not the vehicle will turn over will determine what the next step should be. If the engine does not turn over, I would...

Hi there. Typically when this situation occurs, it's caused by a vacuum leak. It is very common to either intentionally or accidentally remove a vacuum line while replacing a mass air flow sensor. What I would recommend is to retrace...

Hello. This may be related to a faulty idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement). As you may know this is a unit that monitors the air intake into your car's engine as it is mixed with fuel. When this is not...

Hi, thanks for your question. If the axle has the retainer clip on the end of the inner joint but will not stay in the differential, then the differential may have been damaged from the accident. If you would like...

Rarely will pulling a fuse disable an anti-theft system. If it were that easy, thieves would figure that out quickly and more cars would be stolen. Fortunately, most factory alarms are usually fairly simple to diagnose but very difficult to...

Hi there. If the vehicle is just randomly turning off like this, it is almost always caused by a bad crank position sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-crankshaft-position-sensor) on this engine. This is very common and it will not turn on the Check Engine...

Hi there. This can be caused by the issues that you mentioned or a number of other things. You need to make sure all of the connectors are making good contact. I would then need to know what codes are...

Hi. Since the reverse lights turn on when you shift into gear, that is a clear indication that the mechanical portion of the shift linkage is working. I believe the shift solenoid inside the transmission might be stuck open or...

Hi. The air conditioning system works by removing excess heat from inside the vehicle and transferring it outside. There are countless reasons your air conditioning might not work, from a failed compressor to having a low refrigerant level. A trained...

The check engine light is supposed to come on if the controller detects a problem with the car that would effect the vehicle emissions. So it warns you of bad sensors, air leaks, misfires, overheating, and that sort of thing....

Hello, thank you for writing in. Unfortunately, there are a large number of components that can cause this. The vehicle needs to be scanned for diagnostic codes. Even without an engine light on, there may be code present pertaining to...

Hi there: The Service (or Service Engine) light is a warning light that is connected to the engine control unit (ECU) of a vehicle. The ECU is the brain of the car and monitors a number of systems, including mileage,...

Hi there: On late 1990's Nissan's and Infinity models, there are sometimes issues with electrical relays that transmit electrical signals from the power source to individual components. I'm not sure if this is exactly what is going on with your...

Hello. There are many things that can cause a battery to drain even when the car is off. If any live wire on the vehicle, there are many, short to ground then they can complete a circuit that will place...

Hi there. Typically when this engine does this, it is either because the timing chain and tensioner is failing, or it may have a more serious internal issue. The timing chain (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-timing-chain) is by far the most common cause of...

Hello. If this happened right after moving, then the computer may still need to adjust to the new elevation. The computer has an adaptive memory that must adjust to the elevation. If that is not the cause and if you...

The first thing that came to my mind was the Mass Airflow sensor, or MAF. This sensor is located in between the air filter box and the intake manifold. It is the primary sensor input for the amount of fuel...
