Question about 1991 Honda Prelude
The check engine light comes on and then engine idles up and down. could this be a problem with pcv valve?
I dont think it is the PCV but its a good idea to replace the PCV at least once a year either way, and its very cheap, usually $2-$5 at autozone.

There is a warm up valve on the throttle body(should have 2 small coolant hoses). remove the valve and have someone start the car while you block the port to the valve on the intake. If that clears up the problem you can cut a piece of cardboard to mount in between the valve and intake.should straighten it out.

Remove the pass side kick panel (Plastic Part) that would be near the right of the passenger's foot. Locate a small blue plug. You jump the terminals together inside the plug with a paper clip. THEN, turn your key ignition on to power up everything but don't engage the starter. Count the amount of times the check engine light flashes. It's like morse code. A solid longer blink indicates the amount of the first number... a quicker flash will indicate the second number. Here's an example: ___ _ _ _ _ That would be code 14. Let me know what code you get and write back... I don't have room to list every code for 90-91 Accord. I'll check back frequently.
