I'm having an Idle issue with my 92 Accord LX.

It Idles around 200-400 rpm. It accelerates, decelerates, and drives just fine, no problems at all. It doesn't Idle erratically (bounce up and down) though it has temporarily when I attempted to adjust the Idle Speed; my guess is that was the ECU trying to compensate.

I'm thinking this is either a vacuum problem or an electrical problem. I can rule out the Distributor Cap and the Main Fuel Relay. I cannot, however, rule out the Distributor itself. I want to jump on the IACV but I've been told this might not be the problem at all.

Anyone have any experience with this sort of issue? I'm getting a headache trying to diagnose the problem. Any help, suggestions, or advice would be apprectiated. Thanks!

 

do you have a vacuum leak? or you can reset the computer can make your idle normal (500 rpm - 750rpm).

 

Yeah, I'm looking for a vacuum leak. Never had to do that before, but I've been told what to do. I'll try resetting the computer, see what that does. thanks!

 

Daniel, My 92 Accord EX has the same problem. I've replaced the spark plugs, distributor cap and rotor; and spark plug wires. I think it may be the IACV or fast idle valve. I haven't cleaned those yet. Let me know what you find out on your end. Thanks!

 

Cool, I will.

I've been told those aren't the problem, but I'm going to look into the anyway. I'll be checking my vacuum system within the next few days when I get a chance. I'll update on this thread. Thanks
