Re: 2008 Lacrosse P0300 code runs but terrible

Thanks- I just found some other information. I checked the spark and there is no spark on wires 1 and 4(lower coil). I switched the coil pack and the problem is still on 1&4, so It points to a bad Ignition Control Module. I get 12V on the lower pin of the primary, but most likely no switching on the other pin(didnt check that, but the known good coil worked so it must be bad. Is there any other reason that would cause this? I'm thinking it has to be the ICM?
Thanks Again
