i have a 91 hatch with a z6 in it and when i start it it idles at like 200 rpms and wants to die when i give it gas. then when the motor does die the iacv makes a high pitched humming noise. can any one tell me why? also how do i check cel codes when i have an obd0 car with an obd1 ecu? any help is appreciated thanks.

 

also right after the motor starts the cel comes on then it stays on. if i turn the key off the light goes off untill i start the motor again and it dies. anyone know what this could mean?

 

have you tried just cleaning the iacv mine was acting werid sputtering and **** throwing the iacv code and I cleaned it and it was fine.

That means your CEL is ON! (not to bash you but that Q. was pretty dumb) If you convertd to OBD 1 your should know what pin numbers on the ECU jump together to get your CEL to flash whatever code it has stored.

If you converted your car to OBD 1 w/o out even knowing about the CEL.....then man your in over your head and need tech to help you out so you don't mess anything up. This is a perfect example why it is SOO important to research thoughly before doing work to your car that is over your head.

 

ok its not over my head. i just didnt know how to check the codes. i found out how and im solving the problem so its cool. and i know about the cel. ive done plenty of diagnostic work. just not any with an obd1 ecu in an obd0 car.
