how did this occur, tell me some history on the motor, or did you just buy the car and you are walking into the door not knowing a thing just like me. has the timing belt been changed, or has it really needed it?? if it hasnt been changed, it may have jumped a tooth, it will cause it to idle very roughly and miss when under acceleration. when i said is the timing off, i meant the belt its self sorry for the confusion. let me know.
