94 high idle problem
 

I have been seaching the forum for about 3 days now gathering all the info I can about my problem. Before I attempt any of the proposed fixes I just have a few questions. Ok my 1994 Accord coupe idles at 3000 RPM's. We unplugged the map sensor and the car idles at 1200 RPM's. So here is my question: should I spend the money to replace the map sensor, or is it another problem?

well I don't understand it idles when the car is not moving. Doest do it by it self. Cause if that is the problem, I had the same problem with my 94 accord. Come to find put was the distributer. If u car idles by itself u should change the distributer. This cars tends to do this when the distributer is about to die.

it idles like that as soon as you start it up. and when you depress the clutch while you are driving,.

yeah, and goes up and down.. let me ask you a question, when its idling with out u pressing the gas, does your check engine comes on. if it does, is the distributor. so take it to your mechanic asap, other wise you can have a bigger problem. it should cost you around 100 dollars to 150, it shouldnt cost you more than that..

Acctually it just holds steady at 3000 and I get no check engine light. But thanks for the help. Its just another thing Ill have to give consideration to while diagnosing the problem.

I think I've put something in the DIY section about setting your BASE idle. Try that.
