Injector plugs crossed!??!?!?!? Holy shnikeys batman I had no idea that could actually be an issue. I am wondering maybe it that's what's going on with mine too. Anyone have pics on which injector goes where? Some of mine have like a weird little green wrapper and a yellow one and a red one not sure if that was like a coding you did Dee? Or if they come like that from the factory. I think I may have like the 1st 3 injectors mixed up possibly or maybe just the middle two. But yeah had no idea that actually hindered performance though. Also try hooking up the knock sensor as well(worked for my stalling situation). Do you have your 02 sensors hooked up as well? I disconnected mine and it actually seemed to run a bit better for some reason.

Cylinder 1 = white wrapper
Cylinder 2 = Yellow wrapper
Cylinder 3 = Green wrapper
Cylinder 4 = blue wrapper

I think thats an oem feature of the harness, it matches the wire colors of the injector. That was not my issue, however.

Thanks for the info on the injectors :yesnod . Any progress w/yours? It almost sounds like it's a vac. leak. When I first got my setup I had the same issue. It would run for like 15 seconds then fall flat on it's face. And it kinda sounds like what you were describing as happening. Think you might be able to take some pictures up close of all your vac sources and lines? maybe we might be able to compare them to our setups and see if anything is missing/unhooked? Just a thought.

Ya my engine is running fantastically. There was one pretty major vaccuum leak right at the AAC valve, so that was likely causing most of my problems. The reason I did not get throttle response was because the geniuses at the shop tha tbuilt my IC piping left the tape over the throttle body when placing the piping/coupler on. *SIGH*
