my car popped up a cel while driving down the highway. i checked the ecu to see what code it's throwing and i get nothing. no blinks. so i turn it off and check again to see if there is a code. it doesn't even blink once when i turn the key to "on"
ahh this car is pissing me off.
save me before i turn to a dsm.
car: 88 prelude si

It could be your PGM(ECU) thats malfunctioned. Check the codes for the OBD0. I have a OBD1, and my honda service manual says that when this happens, its the ECU. Hope this helps.

 

I had a OBD0 pr3 that the red light stayed on and did not blink. That means your ECU is bad. Is you car in limp mode? will it rev past 3k?

Try another known good ECU.

no, the light on the ecu doesn't come on at all. it goes good and all, i can rev it hard, it's just that driving constant speed, the cel comes on.
