So your TPS right now doesn't even work? Your ECU will fail safe into a preset config if you unplug the TPS. I believe the TPS fail safe is telling the computer that it is wide open throttle when it is unplugged. Can you drive it unplugged? I couldn't even get mine to start when I unplugged it let alone drive it. Say it does start... I don't even know if it will idle or rev up. It will maybe rev up but cruising it will be running way rich

it starts and runs fine when unplugged.

just drove it around a little bit havent had any problems yet

except that i need a new oil pressure gauge again
(maybe its time to get a manual oil pressure gauge because the car keeps frying the oem ones...)
