half engine light stock

I took out my procede and put the car stock, but now I'm getting codes 305, 304, 303, 302, 301, 300 and 135. Needless to say the half engine light goes on and my car shakes because of the misfiring going on. I was careful disconnecting the procede and making sure I put the wires back in the same spot one at a time and double checking. Do you guys have any idea what could be wrong? Thanks in advance.

Triple check your wiring.
Did you take out the v2 PROcede or v1?
If v1 check to make sure you hooked up the correct vacuum lines to the correct solenoid boost nipples. (The long one goes to the nipple closest to the firewall).

What do those code #'s mean/say anyway?

If the car was fine before you took the procede out, your wiring is off. Go triple check everyhting and make sure all the pins are in all the way and in the right ports.

It was v2 so the vacuum lines are back to stock. BTW I'm taking out v2 just to try SSTT since v2 has so much power its just too easy to be speeding. Thanks for the help and congrats on the win vs the R8!

Thats exactly what I'm thinking. I'll do what you suggested, but I was just wondering if I got the wiring wrong would I throw other codes besides the misfire codes? Also thanks for the help.

Cool.
It's your wiring most likely then.

Thanks, that R8 was sick sounding.
I had a front row perspective and opportunity to hear it as it was right along side me and I had my passenger window all the way down to listen to it roar as I started to reel him in and slowly pass on by.
I kinda felt bad for him, he was a cool guy.
He gave me a nice wave as we parted after he lost a second time too.

Do a search for "procede cheat sheet" and it will give you the correct slot # for each wire along with a description of what the wire looks like.

Sounds like you have the wires that were intercepted by the yellow loom reversed when you put them back into the ECU subconnector. Which basically means that your o2 sensors are reversed. The car will drive okay for a few miles and then it will idle poorly and throw all sorts of misfire codes. Easy to fix. The cheat sheet will tell you which wire goes where. Each wire is identifiable by numbers stamped on the insulation.

Thanks Shiv and the rest of you. You are right Shiv wire 6 #525 was mixed up with wire 7 (with no number) in the black subconnector small ecu. I'm idling my car right now and everything seems to be fine. The cheat sheet is invaluable. Thanks again guys for your help!
