the '95 Chevy TBI motor / 4l60e trans will not run correctly. It seems to be running rich, computer in limp mode? The speed sensor along with the speed buffer and the brake sensor is not hooked up yet, but the O2 sensor is.

Has anyone messed with a '95 TBI with auto?
What wires must be hooked up to run the motor along with the trans?

I used a '97 EFI Toyota truck fuel tank and pump.
What fuel pressure does the toyota run at?
The chevy runs at 12 PSI right?

Any advise would be great, leaving for Moab in three days!!!!!!!!

i didnt want any of these probs thats why i used and older simple th350 and got a wiring harnes from centech that only had the wires i needed, no tranny stuff speed sensor or emissions stuff.
