ok....i sold my car to my cousin...
and he said the car is hesitating when hard acceleration....means when you put gear on 3rd, 4th or 5th..and come off the gas, and push gas pedal suddenly, car is hesitating to run...shaking back and forward....any solution? might be pressure plate or fuel injector or something else that i dunno? thnx in advance....

 

Hesitation is one of those symptoms which falls into the "Driveability Complaint" category. These are difficult to diagnose because so many different things can cause them. However, the problem is not with the pressure plate. The pressure plate is part of the clutch, and this is an engine problem, not a clutch problem.

Has all scheduled maintenance been faithfully performed? Did the Check Engine Light ever go on? Are there other symptoms? Does the engine start readily and idle smoothly? Does it have good power after the momentary hesitation?

Possible causes include
- weak fuel pump
- clogged fuel filter
- sticking fuel injectors
- "tired" Oxygen Sensors
- bad Mass Air Flow Sensor
