my car has been jerking, i had the diagnostic test done and all it said was the knock censor was bad, but i know that would cause it to jerk. i took it to a mechanic who said it was my motor mount ( which i don't trust that). my VTM-4 light was on and would go off and now it won't come on at all.
What causes my car to jerk? on 2001 Acura MDX
Find one mechanic you trust is best I can offer. Too many different things could be your problem....guessing wo't help you.
Under what conditions is the 'jerking' ocurring? At take-off, low speed accelleration , 35-45 MPH with very light throttle? Bad motor mount would cause a 'thump' on take-off. Faulty knock sensor could cause poor performance issues , which could then , by default , disable the VTM-4 system while problem ocurrs, turning the vtm warning indicator on. Post diagnostic codes(not descriptions) if possible.
