I hav had a 1996 LX Honda Accord and a 1997 EX Honda Accord. On both, I had the same problem with with a "rough idle". A friend who works for Honda here in South Florida, tells me that what it needs is an adjustment on the throttle and it has to be someone very familiar with the car,otherwise, it may create additional problems. Furthermore, I find this to be a question that needs to be answer by a Honda especialist. many of us are having problems with the "idle" but every mechanic I have talked to, refuses to give me a straight answer. They want to "clean" this, touch that and after several hundred dollars, you still have the same problem. I have been trying to get the email for Honda executives, to see if they give us a solution to this growing problem.

The idle for a 1986 Honda Accord is adjusted by a idle air control valve. These function by either tightening or loosening the valve. This controls how much air is allowed into the system, more air means higher idle and less means lower.
On a 90-93 Honda Accord you can adjust the idle with a screwdriver. On the throttle body there is a screw on the top left above the intake duct. Just adjust until idle is in correct range (usually around 700)

To adjust the idle speed on a 1993 Honda Accord, you will need to locate the adjustment screw which is located on the throttle body. This can stick at times due to obstructions. Once the screw is located, apply carb cleaner to loosen up any debris which may be causing the idle speed to be off.
I have a 97 Hond Accord I just bought and it was idling at 1500 rpm standing still in park. You can adjust the idle by adjusting the throttle cable at the throttle body. There is two nuts on each side of the bracket, loosen both and slide cable until you reach 900 to 1000 rpm range or if you want higher idle adjust it up. If that doesnt fix it check for a vacuum leak. They will also cause your engine to idle higher.
