Q: The door locks no longer work.

Hello! Thank you for writing in with this question. This concern is likely related to the Throttle Position Sensor (TPS). If the TPS is faulty, it sends an incorrect signal to the vehicle’s computer system, which can result in surging...

Yes. Coilovers provide a relatively easy way to fine tune the suspension (https://www.yourmechanic.com/article/how-car-suspension-system-works) on your car. Coilovers typically provide fairly easy adjustability of vehicle ride height and shock damping, depending on which coilover manufacturer you chose. Lowering the ride height...

If the noise is constant, it may be the bearings. If the noise is only when braking, the noise may be brake related. Bearings typically make roaring/howling noises, while brakes typically make squeaking/grinding noises. A test drive and visual inspection...

The engine will tend to run leaner and more efficient when the engine runs warmer. The ignition system like the spark plugs can start to misfire if they are worn. I recommend you seek a mechanic, like the one from...

A code P0411 (https://www.yourmechanic.com/article/p0411-obd-ii-trouble-code-secondary-air-injection-system-incorrect-flow-detected-by-spencer-clayton) indicates a secondary air injection system (https://www.yourmechanic.com/services/exhaust-system-inspection) incorrect flow has been detected. This is essentially a system of flushing clean and fresh air into the exhaust system in order to keep the catalytic converter working at...

Hello. The sensor you had replaced previously may still be the cause of your issues. There is likely something in the circuit that is causing the premature failure of the sensor. Test the sensor the same way you did before,...

The part number for the 3.5L 6-cylinder engine is 8966142G02 and the number for the 4-cylinder engine is 8966142F72. As long as the ECU you're getting matches or cross references the appropriate part number, there shouldn't be a problem. However,...

Hi there. Typically when an engine ticks constantly and the tick increases in speed as the RPM increases, it's an indication of worn out cylinder head hardware (like valve lifters specifically) or a timing chain / belt that is wearing...

Hi There, What you are describing sounds like a fan clutch (https://www.yourmechanic.com/services/fan-clutch-replacement) that may be wearing out. A mechanical fan clutch works by helping to control the radiator cooling fan speeds as the engine heats up and cools down. As...
