Re:Idle air control valve
ok, My car will not idle under 1000 RPM (or my autometer tach is messed) it usualy stays at 1000, and 1500 when warming up. But on occasion the tach needle will shoot to 0and then back to 1000, and the idle will surge. Sometimes it's so bad that unless you keep your foot on the gas the car will die. other times it's fine and the car(89zc, 91 ecu) is completely normal
working on many many cars...

Re:Idle air control valve
ok, my idel problem is a little higher.Most poeple say theres jumps (500-1000, or 1200-down) On my car its stuck at 2800.I've takin off the ICVA and cleaned it with carb cleaner,but it still shoots to 2800. I also sprayed soapy water on all the VAC lines and didn't see no bubbles. Is there a chance its still the IACV or should I be looking somewhere else? This is in a 88'crx w/B16A

Re:Idle air control valve
I finally fixed the idle on my CRX!
Symptoms: Stumlbed on idle alot, almost like it was mis-firing on cyl's. Engine's RPM never stayed constant. Just sounded like complete POOP!
Solution: Replaced ECU, Idles 100% better, and even sounds better when I rev it up.
More or less I took my multimeter (digital volt meter) and a honda service manual and followed the flow chart for diagnosis. Evetually got to where it said to substitute known ECU and that worked!
just thought I'd let you guys and gals know not to count out the ecu.

Re:Idle air control valve
Today I finally got rid of my code. Just put the right plugs on the right sensors. It helps if you look at a diagram and what color wires go where. I got smart about it. But I still have an O2 code. one left. Maybe my car won't run like ---- when I get it fixed.
