Removed emissions, car runs bad at low rpms.

Whizbang · 09-09-2008, 05:18 PM

trying to figure out where something went wrong. I also removed the thermowax, so i expected some cold resistance towards idling but this is also just plaining running bad at low rpms.

Did most of the emission removal (left the spider rack since i didnt have fuel line) but now the car seems to run real choppy up til 2000 rpms.....

I am running the FPR off the bottom vac nipple on the back of the UIM. That showed vacuum on the boost gauge, where as the top two didnt. So i am sure the FPR is seeing signal.

Other than that, the pressure sensor is seeing signal as well.

I can find no obvious vacuum leaks, but i wont rule any out, i just double checked the hell out of everything and i can't find it.

TPS and coolant sensor are plugged in.

any ideas?
