Q: Misfiring

When a transmission fails, the vehicle will seem as though it is in neutral. Sometimes if you rev the engine high it might move slowly. If this is the case of if the vehicle does not move at all, yes...

Yes it really does. Because turbos spin hundreds of thousands of revolutions and they need really good lubrication. They need a little heavier oil (https://www.yourmechanic.com/article/why-are-5w-30-and-5w-20-oils-so-common). They need the 30 vs. the 20 and you don't want to mess with the...

Hello. I think the car is running rough because the Check Engine Light is on. It is possible that the alternator is not working properly (https://www.yourmechanic.com/article/how-to-test-your-alternator_2) causing low voltage, which would make the car difficult to run properly. I would...

Hello. From what you've described, your car has a bad brake light switch. This switch is located on the brake pedal assembly under the dash. It starts to fail and in most cases the smallest amount of movement will allow...

Hi there. It seems like what happened was, when putting the vehicle in 4WD low and driving at a high speed on pavement this could have caused the front axle to burn up. This is because the front differential has...

Hello and thanks for writing in. Code P0174 relates to a lean fuel condition which is typically caused by a faulty mass air flow sensor or potentially a vacuum leak beyond the mass air flow sensor causing the reading of...

For some models, the low oil level sensor will interrupt the fuel pump (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-low-oil-level-sensor) if the level sensor detects a low oil level. Of course, in your circumstance if the level on the dipstick is correct the level sensor and/or...
