Ok I changed engines, long story, the problem now is that I keep blowing fuses. The fuse for the computer to be exact.

This only happens when .......

1) Car is warm
2) RPM's stay over 3500 (can go up and down w/o problems)
3) Only when car is in motion

Any help woud be greatly appreciated. I really miss driving my car.

You keep blowing the ECU fuse?

BIGTRE13

yes sir, thats the only one

supercow

did you swap ecu's as well?

BIGTRE13

no, just the engine

You cut one of the sensor wires and it's grounding out somewhere.

BIGTRE13

which sensor could it be ? the car has been checked by 3 different mechanics and still no luck

when you swapped motors, did you re-use the old harnesses?

BIGTRE13

yes the only thing I changed was the motor

i'm going to make the assumption that it worked properly before. i don't have my electrical manual with me, but if you do, does the ecu fuse you're talking about send power solely to the ecu, or does send power to other sources as well?
