Q: What is the proper tire air pressure for my car?

Have a trained mechanic first verify a proper oil level. This is vital to the engine's operation, as internal components that are not receiving proper oiling can become noisy. If the noise doesn't go away with the proper oil level,...

Hi there. Your transmission consists of many different components. These mechanical and electrical components need to work in sync in order for your transmission to work properly. Your gear shifter may be moving, but if the solenoids internally are not...

With the age and mileage of your vehicle, it would probably benefit from a throttle body service including cleaning the idle air control valve. Over time, oil and carbon build up on the throttle blade so it does not sit...

Hello there, a few common faults can cause your 1972 Oldsmobile Cutlass to only work on the #2 speed air flow. You are correct, the blower motor resistor (https://www.yourmechanic.com/services/cooling-fan-resistor-replacement) could cause this fault. Other likely causes would be the fan...

Hello - your symptoms suggest that the throttle position sensor has failed. This would not be unusual for a vehicle with your extended mileage. I would recommend having a Car Hesitates during Acceleration Inspection (https://www.yourmechanic.com/services/engine-hesitates-during-acceleration-inspection) completed by a mobile, professional...

Hi there - in this case, you have nailed it - it's the passenger side engine mount. The engine mounts on this engine (L & R) are hydraulic, and leak fluid when they rupture. It is possible that both of...

In order for either system to work correctly they depend on the same sensors to work correctly. If one system has a failure then the other system is also disabled and light is turned on. You will need to have...

Hi Joy. Thanks for contacting us today. Usually the "click" noise while starting is an indication that the starter motor is either not receiving power to engage the motor. This could be due to a dead battery, damaged electrical relay...

If the poor acceleration is intermittent, that suggests a cause involving an electrically controlled component including sensors that send data to the PCM. To diagnose this, a real time scanner is applied to view actual engine operating parameters during the...
