Opinion on log file
Had it running well, now not so much. It running really rough. I have quite a shake in the engine. 302, Go Street 400hp, FCC2. Stock ignition with petronix module in distributor. Seems like it is getting worse. IAC was right around 6-8. Last Logfile looked good.
Last night I started checking for leaks and found my exhaust manifolds bolt were not snugged down. Also the manifold to exhaust bolts were loose. I tightened that all up, now my IAC is at 0-1. I can't bring it back up as the TPS does not go negative.
Anyways, here is a log, any input would be appreciated.

Turn the engine off. Turn idle screw counter clockwise 1/4 Turn. Restart.
That resets your TPS and should bring your IAC steps up. Do this only when up to temp.
Your unit is doing it's job. Starting to learn. Doesn't look bad. How is it running now?
So that log looked good? It's running rough. Could there be a vacuum leak? Do my vacuum numbers look OK? I'll turn the idle screw out after work today and update.
Thanks,

One thing at a time. May want to swap plugs or clean them. Exhaust leaks will cause the unit to think it is running lean and dump fuel, thus fouling plugs.
Plugs are new. I pulled three of them and all looked good. I'll check the rest of them later today.
