Idling High and misfiring ( IAC ) ????

I went to Auto Zone to get my diagnosed today. After getting the results, it showed maybe the IAC is not functioning properly. Does anyone know how to check for this or troubleshoot the possibilities?

Why is my 91 s-10 4.3 idling high


check for vaccum leaks on intake manifold. follow brake booster hose to engine and check for leak from there. Also check idle air control (IAC) this is what controls idling on todays vehicles. the IAC may be plugged, sticking, or bad. remove and clean if possible. Hope this helps!

I have a 2002 ford taurus. check engine light is on. Auto Zone did a scan today and the error code was p1507 can you please tell me what i need to do to fix this problem.


possible problems

Vaccuum leak
failed IAC valve
open or short
air inlet plugged

P1507 means "Idle Air Control Underspeed Error". It can be most commonly caused by a vacuum leak, a damaged Idle Air Control (IAC) assembly or a stuck IAC valve that needs cleaning. Essentially, your engine isn't idling at high enough according to your computer's programming parameters. Many times this shows up in colder weather as you try and start your vehicle. It will usually die unless you put your foot on the gas pedal and raise the RPM's. I have also read where a clogged air filter might be the problem. I would try cleaning your IAC valve first.

Stop wasting time at auto zone and throwing parts at it. Find a good repair shop and have it properly diagnosed and repaired.
Have you ever had a spark plug fail in your lifetime?Probablely never will.
Do you know how to test a coil pack? Did you test it?

A simple check of vacuum hoses or a loose air filter cover,loose gas cap an so on ,could be your part of your problems. e.g. something simple.

I would recommend spending the big bucks and getting the shop manuals,for all your vehicles,something no one wants to do. Then study your vehicles systems and eventually ,you may be doing your own repairs.

Idler is too high on start-up, goes up to 2.5-3 rpm. and comes back to normal. just started a week ago. what could be the problem? 2005 Chevy Aveo


I bought my 2004 aveo 49 miles. I've had several issues with the car. But recently I been experiencung high idle at start up and clutching. I change IAC. Plugs and wireds. Nothing worked. Today the high idle became constant. It was a metal bubble flex tube near the IAC unit that goes to the exhaust stuff down behind the motor. It apparently was cracked cause today it broke causing the constant high idle sound like a vacumn. We blocked it off with a stick to get the idle back down to 900 rpm instead of 3-4000 rpm took we can get to auto zone for high temp hose per Chevy dealer. I hope this helps someone cause it was fustrating and costly.
