turns on. stumbles and dies when it gets hot.
ok guys thx for the help ahead of time.. ok i have an 1990 fc S/5 we swapped an 88 s/4 turbo motor in it. N332 ecu.... the car started giving me problems after i fixed the manifold to turbo gsk (started over boosting 15psi stock turbo) found out that my friend kicked my injector ground loose... fixed it... now down to my issue i start it. it runs fine. warms up to normal temp jumps into some kind of limp mode ruff idle and wont keep idle only if i hold the throttle open runs like crap sounds like one rotor.... lmk if you guys ever experienced this befor thx

Water Thermosensor is found at pin 2I (Green/White wire) of the ECU. W/key to on it will read 2 to 3 volts on a cold engine and as the engine heats up the voltage value slowly drops to .4 volts. If one of the primarie clips was damaged then you could basically tell at the ECU if the plug is making a solid connection. Pins 3E (Light Green) and 3C (Light Green/Black) should both register 12 volts w/key to on. And why was your friend walking on your engine? And check for vacuum leaks in the area in which you worked on.
