6G Celicas Forums

Ok so I have been having some troubles with my celica. I think my ecu is going or is dead. Does any one know how to test the ecu?

What problems are you having that lead you to believe something is wrong?

yea i think mine is bad too. i idle at 1700. spent 600 to change something inside the throttle. didnt do diddly squat.

if your car is running, your ecu is fine. if the ecu went bad, the car wouldnt start or run at all.

It won't start! No spark I get gas but no spark. And I just replaced my distributer again (sorry nik my dad thought this would work). So we have been checking electrical, but him and I don't have that much experience with this. We do have a chilton's and we fallowed its dignostic instrucions and it narrowed it down to the ECU, but we both are going to be pissed if we buy a $125 ECU and it doesn't work! Any thoughts, possible other faults in the system, etc. would be a huge help.
Thanks,
TJ

Forkee mine used to idle high too but it was due to a stuck open thermostat which caused it to try to come up to temp constantly during the winter with the radiator cooling the antifreeze constantly. Got reely bad gas mileage too like 25-mpg instead of 31mpg
