is it true that if one goes bad u change them all? i am having problems with the spark plug coil packs thats what i call them. i got a used one about 3 months ago and the same one stopped working again. what do i do? can driving with a bad pack cause my ecu to short out? last time the other one went bad i drove around like that for a week or more and soon after that i burnt my ecu now yes there was a little bit of water involved but what if it wasnt the water that burnt it but my dumass driving on 5 cylinders. god it burns gas like it was free. help please! :runaround:
