Hello all, I've been having trouble with my car (1995 GS). I'll explain what has been going on. I did an engine rebuild, but still the car sometimes idle down and died. I went ahead an changed the Crank Sensor, since the sensor was cracked I thought "I'm on the right track" I had to cut and put the new plug. The car worked fine for like a mile, then it stuttered and died. Took it home, left it there for 3 days. On the fourth day, it didn't start. But if I gave a little knock on the ECU, the car started. I didn't want to use it like that, so I went ahead and bought a used ECU, the car still doesn't start. The electric guy tells me I need another ECU, is there a way to diagnose the ECU to know if that is the problem?

Thanks in advanced....
