Cylinders 7 and 8 fouling out?!!! Any one know if LS1 pcms do anything funny on start up that would cause the number 7 and 8 cylinders to foul out? All the rest of the plugs look fine. I've been pulling it in out of the shop for the past 2 months just to get it out of the way and I started it last night to pull it back in and it started running like ****. I found 7 and 8 soaking wet no spark at all. Any ideas?

Checked the wires resistance and it checks out. I also swaped the coil pack to the front and made no diffrence. I put new plugs in and it seems to be running great now but I'm still worried why it did that in the first place. Oh yeah I am also running a 4 step colder plug for the juice this may also be a problem but I would think it would fould them all out and not just the two. Besides I've been running these same plaugs for a yea now with no problems. This just came out of no where and I just figured it was from all the start ups moving the car around so much.

Do you not drive the car much? With the colder plugs my car will chalk the plugs up(rich),and run a lil rough from moving the car in and out of the shop twice a day,short idles times,and not being drivin much.Have'nt had them get wet though.
