When the engine oil was changed, the maintenance reminder was probably not re-set. Be sure that the level of engine oil is adequate as measured on the dipstick. Misfiring can cause engine and catalytic converter damage so be sure to...

The part in the picture looks like it is the PIP sensor also called cam sensor. The sensor is located in the top of the engine in front of intake manifold and is used to provide a cam signal to...

Hi Dorian. Thanks for contacting us today. The mass air flow sensor itself is an on or off type of component, meaning it either works or it won't. It doesn't take time for the sensor to 'break in'. The issue...

The flashing check engine light signifies misfiring and the engine fault(s) causing the misfiring are probably related to the loss of power you are describing. Misfiring is potentially very damaging and so you should drive at a lower speed to...

Hi Johnnie. Thanks for contacting us tonight. If your AC/Heater will not turn on (meaning the blower motor), then it's likely that you have a blown fuse or damaged electrical relay that powers the blower motor is likely the cause....

The window regulator or motor is the most likely cause of the window not going down. If you hear the motor running, but the window does not move, then the regulator is broken. If you do not hear the motor,...

There could be several reason why your car is smelling like gas. Your car's spark plugs (https://www.yourmechanic.com/services/spark-plugs-replacement) could be very worn out and not firing properly, causing the gas not to be burned properly and creating a gas smell in...

Hello. The firing order of your car is 1-3-4-2.

As bad as that sounds, it could be as simple as a worn bushing which would cause the cable to come loose from the linkage. It may have also been a broken shifter cable. So the first step would be...

This may be a sign of low transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) 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...

OBD-II trouble codes, including all codes that refer to oxygen sensors, do not constitute a diagnostic or identification of specific failed parts. Consequently, you cannot use the codes as the sole basis to replace vehicle parts. Codes are clues only....

Hi Rebecca. Thanks for reaching out to us tonight. When a vehicle stalls and loses electrical power like you've described, it can be very tricky to diagnose, since there are so many possible sources. In many cases, this can be...

To answer your question: maybe. The throttle body has some redundant circuits in it that might make it possible to operate in a "limp home" mode, but unless the owner can have the car repaired and verify the repair before...

Hi Pedro. Thanks for contacting us today. There are a few possible things that can cause these symptoms. The most common would be that you have a mass air flow sensor that is clogged with excessive carbon deposits, a vacuum...

If none of the windows are working from any of the switches, there must be a common circuit problem. The first thing I would do is check the fuse. Fuse information can be found in your owner's manual. If the...

A loud knocking noise coming from the engine can be any of several issues. Having to put 5 quarts of oil in the engine means that the engine was completely empty, basically. The engine oil's main purpose is lubrication, and...

The easy way to do it is to replace the hub assembly (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-wheel-hub-assembly) if you have a lot of miles on them since it will give you new studs and bearings. If you want to just replace the studs, you...

If the hazard warning lights use the same bulb (filament) as the turn signals, then yes it can't be the bulbs. I would test the turn signal flasher unit. Basically, you want to test for power to the flasher unit...

The transmission in your Pontiac uses solenoids to control the shifting from one gear to the next. Typically there is a solenoid for 1st and 2nd gear, a second solenoid for 3rd and 4th gear and a 3rd and 4th...

An appropriate diagnostic to resolve your issue is a failure to shift inspection (https://www.yourmechanic.com/services/not-able-to-change-gears-inspection). Of course, first check your transmission's fluid level and condition (https://www.yourmechanic.com/services/transmission-fluid-service). A really low fluid level can cause shift difficulties. Typically, if a transmission fails to...
