I tried regrounding off the black wire on the MAF, didnt do anything .

I would switch PCMs with someone, but there isnt anyone in my area to switch with

Is it possible that when I blew the fuse I screwed up the PCM somehow??

Doubtful, given the fusing. You got a factory service manual? I'm thinking check all underhood and fuse panel fuses.

its normal for the idle to hang high when u drive around and press the clutch in....you can kinda fix it by messing with a IAC vs mph table in LT1Edit. I got mine to drop almost back to 1k when i press the clutch in when i am driving.

Chris I think you need to focus on the computer related problems you are having. You messed up something when the O2 wire smoked and I dont think you lost a rocker at the same time. We need to go back to the computer. Call Brian over at pcmforless.com or Ion over at madz28.com and talk to them about getting a computer sent out. Ion doesnt offer this on his site so I think you gotta ask him about it. might just take a day or so to get it to you.

this would also be a good time to get those performance mods done to the computer you might have been putting off

My computer is tuned for all my mods....

When I replaced the O2s the car quit running rich, now the idle just hangs around 2000 until i stop, then it falls back down. It has no driveability issues anymore other than that, and Ive been told by several people that comes from the cam I have, and that all big cams will "hang" up like that. So I think everything is fixed.. The O2 replacements did solve the problem of it running super rich though
