Did a search, but couldn't find anything specific to this problem, although I do know that the caps in the ECU give problems.
I have a 1992 Levin 20v here, the check engine light came on and the car lost power. It would still go and start but had very little power.
Anyway, I tried to check the codes by bridging TE1 and E1, but the eng light would flash erratically or would stay be on but dim like it was trying to flash very fast, no two times would it blink the same, I've read plenty of codes from engine check lights but this was just random.
So I put the car in the garage to check it over, and now it won't even start, just cranks over.
I've pulled the ECU out and opened the lid, but the caps seem to be OK. I'll upload a pic.
