2000 Accord Idle Problem
So my 2000 Accord is having an idle issue after removing the IACV ( idle air control valve ) and the EGR valve for cleaning. For the past 6 months my car has had issues idling. It started to happen mostly when it rained or the road was damp. It started to happen more and more frequently, me pulling up to stop signs or stop lights and my rpms dropping, stalling the car out. It would always start back up just fine and then wouldn't happen again for weeks/months. Just recently it happened and lasted all day instead of going away like it usually did. I thought that right off it may be my distributor since it was raining that day. I checked it and everything seemed fine. No moisture and all the leads looked to be in good shape as did the rotor. So the next day I took it over to advance auto and had them run a scan on it. It threw up 4 codes. EGR valve, O2 sensor, Cooling System Malfunction, and a valve timing code. That day I took off and cleaned the EGR valve and the IACV. I also replaced the plugs and wires. Im thinking that my cooling system malfunction may be air in the coolant so I plan on bleeding the system tomorrow. I haven't checked into an O2 sensor yet so that may still be the problem. Anyway after putting the clean EGR and IACV back on I ran into another problem. I started the car up and the rpms started jumping from 1000 - 2000. Not only was the needle bouncing up and down but the engine was reving also. Im thinking I just didn't let the IACV dry all the way before putting it back on. Whatever it is has me stumped. Im thinking the EGR or IACV needs to be replaced and the cleaning just wasn't good enough. The valve on the bottom of my EGR valve pushes in and out with my finger, I don't know if thats a good thing or a bad thing. My IACV has a slight opening in it and doesn't seem to close all the way. I sprayed both with TB cleaner hoping that'd do the trick but Im not 100% sure if that helped any. If anyone has had this problem then please share your storys, Im trying to gain as much information as possible for troubleshooting this, Thanks.
