04 GTO rich idle/ dies with any throttle
Car has head/cam build recently with what seems a not so good tune. In the beginnings the car wouldn't hold an idle for the life of it. It was throwing a p0101 code. Cleaned the MAF and the KN filter and haven't seen the code since. Also now the car will start and idle very rich with no problem on a cold start. as the engine warms if you hit the throttle and give a little rev to the engine when coming back down to idle it will just die like I turned the key off. After this the car will not hold an idle at all. Very hard to restart and will only run with slight throttle. Ive checked every nook and cranny for a vacuum leak with nothing. As of right now this all the info that I have. I know a log would preferable but I don't have the software for that nor anyone close with hp tuners who can scan it. Any help, guidance, or direction would be very appreciated.
Thank you

So with that saying, your best bet (unless you really just want to start throwing money at random parts and hoping it fixes things) is to get some sort of scanner on it and do some logs.

Thanks for the help... I may have a maf issue. I found if I unplug it there is no real change. I also found if unplug the IAC and start I have no issues with idle. I I plug it back in and it still idle fines. If hit the throttle it will hang at 2k rpm then slowly come down to idle. Could all these be related to a bad maf?
