If you are referring to the stuff on the side of the super charger, I have been egr deleted for a good 8 months without a problem. I had vmp send me a hand held with a tune also turning all that stuff off. That's why I was concerned about the tune getting messed up after plugging the battery back in. I spent the entire day checking everything and rechecking all brought to my attention. I have searched the forms also, we will find it with help and probably find something simple. I know there aren't any vacuum leaks that's for sure. I just wish I could have gotten those original O2's out, I still believe my problem has something to do with them. Other then exhaust swap they were the only thing's that were changed. I also read some guys got the same code when they lost a coil, but all mine are good after checking. Now I did unplug the IAC and there wasn't a change in the engine idle at all. It didn't die or speed up, took it off and it looks to be new inside and all moves free?? Still searching, I may call vmp Monday and see if they can e-mail me the tune and I can load it and just put my mind at rest about the tune getting jacked up from the battery being unplugged for a day and then plugged back up. I really don't understand all this trouble from a simple header/mid pipe swap when everything was so good before. I will also be replacing the IAC just because I thought it should do something from being unplugged. Thanks again for all the help men.
