Yeah he has been a big help, but I know he is super busy and I hate to keep bothering him with basic questions when I'm not going with the fast system (not yet). I got a scanmaster and did a lot of reading on this site but I can't get my IAC to adjust it stays over .50, I set the TPS and welded up my leaking ex manifold, and replaced my valve springs (Cals suggestion) I'm not sure if I have a bad iac or MAF, but the car is running lean and only goes to 10psi and will spark knock at 10psi.
