sorry i am kinda new at this my husband works nights so i am trying to fix it!!! i am trying to fnd it so we can have it tested autozone told my husband to bring it in!!! at irst we thought it was the icm and then icalled autozone and they said it didnt have one. the 3rd cyl. was misfiring so we changed the 3rd coil and thespark plug but now it is still misfioringso they said it could be an icm or ecm poblem!!!!
my husband will be home at 5 am cst maybe then i can get him to help me record what is doing and post it !!
first of all, autozone is a parts store with parts salesman, not technicians. you need a shop that has technicians that will pinpoint your failure and repair it correctly.
autozone cannot test a pcm off the car.
