testing spark plug coil packs?
i've heard of stories of coil packs just going bad after xx,xxx miles. is there any way of testing them to see wether or not they have gone bad? any advice would be great cuz i just tried changing the spark plugs and got bad misfiring. i put the old ones back in and im still getting the misfiring. i suspect it may be the maf sensor or coil packs. thanks
