High idle on 86 Ford Bronco II (2.9L). Have replaced IAC, TPS and ECT. Also checked all vacuum lines. No fix. Need help.


I have heard of coolant sensors staying cold and keeping idle high but not a particular model.

How to fix problem with cod P1506 Ford explower 1998


Hello! The Idle Air Control (IAC) is setting P1506...Idle is to high...Other problems can cause the idle to over speed...It isn't the IAC in many instances...A vacuum leak is #1...The vehicle has some years on it...Go over the vacuum lines and look for weak collapsed lines, broken, or poorly seated...A defective PCV valve is #2...If it hasn't been changed in awhile it's due...Base idle should be 780 in neutral...If # 1 and #2 prove to be OK I'll take it from there...

Car idles up and down @ stop wen i give gas it bogs down i have to let my foot off the gas pedle


find the idle control motor on top of the engine and remove it, most times you can clean it with throttle cleaner sold at auto parts. and if that does not work replace it.

1986 Honda Accord DX - too high idle on cold start


1986-1989 Honda Accord with Carburetor have a very bad habit that is little known even by most mechanics but easily fixed at home. The vacuum port on the choke opener that is connected to the intake manifold and both vacuum ports on the fast idle unloader get plugged up with nasty hard carbon almost as hard as metal. When this happens the choke sticks closed and the idle sticks on fast idle when the engine is cold and nobody can figure out why. All you have to do is attach a small drill bit to the end of a flexible socket-driver extension and put it in a variable speed drill that will let you run it real slow and carefully drill out the vacuum ports that are plugged. After they are nice and clean use a vacuum pump tester to make sure the choke opener and fast idle unloader are working before putting it all back together. It's amazing how much better the car runs after cleaning out those ports.

Fuel injector needs to be cleaned maybe?


First Replace your Gas Cap. It has a Leak around the Cap causing the Erratic Idle. Next- Go to Wal Mart and Purchase 2 Cans of B12 Chemtool in the Automotive Section. Run 1 Can at a Time through a Full tank of gas. This will help Tremendously!
