Alright... I have a '99 Accord LX i4 with F-Max setup. The car runs perfect under boost, actually it runs perfect as long as I'm not idling. I've had numerous ppl listen in and no one has heard pingin or knockin or anything, but I'm gettin the follow check engine codes: IAC Valve, cylinder 1, 2, 3, 4 misfiring. Now I talked to local Honda service guys and they said that its probably not misfiring... just hte ECU throwing whacky codes. But the car also surges. It surges from 1000RPM to 1500 RPM at idle. So I did take off the TB, cleaned it with carb cleaner, then took off the IAC Valve and shot a bunch of carb cleaner but it looked brand new. I cant figure out whats goin on.. Any ideas? After this I'm just gonna take it to a local tunin shop.
