Help!!!
The other day I reconnected my airpump to the cat-convertor to try to pass emissions, and everything seemed to be fine. The car continued to run as normal, however, I shut it off, took it down off of the jack stands, fired it back up, and now it is running like crap. It seems like it is running really rich. I actually have a mist of fuel vapors coming out of the exhaust after shutting it off.
Initially it was idling really rough around 1500 rpm but it settled down and began to react somewhat normal again. Except for the smoking.
I began to trace down vacuum lines, and found nothing over the last day. Then, all of the sudden, I started it up again, and the smoking was gone, the idle was smoothe, and I thought the problem was gone.
Wrong I was!
Took it for a quick test drive around the block and it is backfiring like crazy when I let up off of the throttle. It also stumbles around 3-4000 RPM. (Similar to a fuel cut)
The car has the following installed:
-Power FC w/commander
-PF intercooler
-Pettit intake W/ K&N's
-Downpipe
-Highflow Cat
-Cat back exh.
I also just installed new plugs and cleaned my K&N airfilters. I only run high octane gas, and currently I have some octane booster in the tank as well. I am at a complete loss at this point and I am trying to remain positive that it is something simple.
Please help if you have had similar symptoms or any ideas I haven't tried yet.
Thanks in advance.

Hey I ran into something similar w/ my car... run around in your PFC screens untill you see somthing named option 5 in there and see if it is selected or not if so deselect it and hopfully that will do it... you PFC probably did some CrAzY learning mode ****.... ps if your car is tuned don't reset the ***** or you'll be there for about 2 hours re-inputting the maps if you have them on paper... Hope this helps you can also pm me if you have more q's

Well, anyone else that has a Power FC, and may have this problem, it was the option that was selected that gave me the problem.
When I was browsing through the settings, I didn't realize that the option that is highlighted, when you hit the previous button to back out of the PIM Voltage settings, would be the one that would take effect. I changed it back to normal and now my car runs great!!
Thanks wonder1and.
you saved me a lot of money, I was about to take it to the shop at $80 an hour.
