Sounds like it could be your Idle Air Control valve (IAC). The IAC does as it sounds and controls the idle in your vehicle. When these go bad, you can either clean them with a throttle body cleaner or replace them. Most people replace them as they are normally not very expensive and relatively easy to replace. The IAC is located on the throttle body which is where the air duct hose ends as it comes out of the air filter box. It is normally held on with a couple screws and just needs to be unplugged and plug the new one in. Please, please let me know if you have any further questions. If you can't find the location of the part let me know. Also if you don't think the IAC is your problem and have addition information that could point to something else, let me know.

This is the IAC for the 6 cylinder engine but it is different and more expensive on the 4. Let me know if you have the 4 and need a picture of it. Thanks for rating my response and for using FixYa!

2003 ford escape over heats while idleing


There are a few things which should be happening to prevent both problems.

There is a fan relay which senses heat and then turns on the electric cooling fan. Around this time, an idle control should cause the RPM to increase to help circulate the water in the engine.

Sounds like the engine is getting too lean to run because these automatic controls are not working. The hot engine is running lean.

My ford escape idle very rough. it accelerates fine. i need help to solve the problem


If your Escape is v-6 powered a common problem believe it or not is a solenoid in the transmission that allows the torque converter to "unlock" at idle. If the solenoid is bad then the torque converter stays locked and puts a load on the engine causing rough idle in gear at stop.

Check Engine Light on Yr2001 Ford Escape V-6 2wd. Code says: Misfire on cylinder #5. Dealer said compression is low in cylinder #5. This Escape needs to pass smog. What can we do?


If the engine has a P0305 DTC (Data Trouble Code) for a "cylinder 5 mis-fire detected", then the first thing to do is to do a compression test to determine if the mis-fire is actually being caused by a mechanical problem, or an electronic problem.

If the engine really does have low compression on the #5 cylinder then that is caused by a mechanical mis-fire and nothing electronic will repair it, and the most common causes for a mechanical mis-fire would be a burnt or bent intake or exhaust valve, a warped cylinder head or damaged head gasket, or a damaged piston. You can call around and find a repair shop that will do a "compression leak down test" if you want to know exactly what is causing the compression leak without any dis-assembly to the engine.

My 2002 Mazda MPV recently developed an engine shake when stop at intersection or driving 45mph or slower. My mechanic scanned and found OS2 code, vacuum leak, replaced the intake hose, reset engine...


You might try another mechanic if this one can't get it fixed. Shaking is usually caused by one or more cylinders mis-firing for whatever reason--usually faulty ignition or fuel injection. Has the engine had recent tune-up? Bad spark plugs/plug wiring are frequent villains. Not sure what an 'OS2' code is. Hope this helps!
