How do I fix a high idle on my car?

Question

When I start it its above 2000rpm and I usually wait for it to get close to 1000, its an 87 acura integra, any reasons for having a high idle and any advice on how to fix it?

Answer 1

The idle should be higher when you start a cold engine. After it warms up it should typically idle at 750 RPM. If it's idling higher your shop technician can hook up his scanner to your computer and see what engine operating parameters are not reading normally. You could have air leaking around your air flow sensors or an idle air control problem. The computer scanner will tell him where to look for a problem.

Answer 2

That's a normal operating characteristic of any Honda/Acura motor. They all do it. It's to help warm them up faster and to prevent it from stalling when cold. It normally comes down pretty quickly though depending on temperature. As the engine warms up, the idle comes down.

Answer 3

Yes, it can be fixed. But I strongly recommend you take it to a mechanic. For a tune-up like this, it should not cost you too much. The reason I'm suggesting to take to a mechanic is, if you don't do it right, you can cause the engine to stall when climbing a hill or something stressful on the engine.
