My 88 Integra ECU is blinking non stop, with no decipherable (sp?) codes. Its running a turbo DOHC ZC on the hack. I have a one wire DSM o2 sensor hooked up to the stock engine harness. The CEL comes on intermitently, and goes off when I turn the car off, but the ECU does have memory. The CEL only comes on after a decent drive, and just with normal driving. Whats wrong?

 

I had a code 9 on my 1989 Integra LS this May and it turned out it was the crank angle sensor, just as the manual said. Are you sure there is no discernable code?
Try to count the differences of short and long flashes. If you are sure there is no pattern, then I can't advise you other than to tell you what the manual says, "take it to the dealer." Bestof luck!

 

Nope, there cetaintly wasnt any codes, just flashing.

Anyway, its gone now.
