Well, I replaced the egrthe iac, and the little sensor that goes to the egr. it was doing the same thing but not as bad. I replace the fuel pressure regulator and its running great! my headers and muffler come in tomorrow hopefully and ill be driving it to work and back again!

wait....you said you were basically running open headers, but your headers come in tomorrow hopefully.........please don't tell me you were running open exhaust runners, that's a big

Glad you figured out your problem though....it must've been a bad spring in that regulator.

Nope. Open manifolds..not good either but my long tubes should be here(according to fedex) today! Yea when i pulled that regulator off that spring was worn outtt. All the gaskets were bad too on that throttle body.

Wow. I got the long tubes in and Flowtech red hots that dump right before the doors end..and keep in mind that I have an extended cab! It sounds mean as hell. Lol its runnin good though. I really appreciate the help yall!
