Re: How to test ignition coil pack
when my coil pack crapped out, i had a miss that you could really feel when the truck tried to downshift.... but it idled fine, in fact i would up driving around with it like that for over a month before it got really bad and FINALLY threw a code.... also wound up fouling out the one plug really bad.
i think i would start by pulling the plugs and looking to see if one looks like it's not fireing correctly, like it's got crap built up on it, ect.... that could help clue you in. have you done the plugs & wires recently?
