Can you clean the idle air control on a 2002 Ford Escape

Yes you can clean it out, but as always, there are some things to be aware of in the process. Use carb cleaner, not gasoline. Do this not only because it will work better, but for safety reasons as ...

RPM wildly fluctuates while idling

The comments are correct. I would start by cleaning the item in the lower right in the diagram below from underneath the intake plenum. Remove it completely by disconnecting the electrical connector,...

Ford may be trying to match the engine speed to the transmission shaft speed. This would tend to reduce wear on the clutches. When the transmission is shifted back into gear after a down hill run in ...

Renault Clio 2002 high idling on startup

I had exactly the same problem on a Clio with similar generation. The contacts of the sensor were oxidized. It was not necessary to replace the sensor, plugging it in and out several times solved the ...

Very high RPMs when in neutral and moving - Manual transmission

Im going to bet that you did not replace the IAC with a new Motorcraft brand. There is a large batch of aftermarket ones that are causing the exact symptoms you describe. You were probably correct ...

engine rpm stay far higher than idle when hot

It sounds like the carburetors are sticking when hot or you have an air leak between the carbs and the head. I'd recommend using an unlit propane torch, or something like WD40 or spray carburetor ...

RPM wildly fluctuates while idling

Did you replace the EGRC-BPT valve? Also, you might swap in the old EGR valve (or a different one from another manufacturer) because I was once sold the wrong part number for my EGR valve. Did you ...

Very high RPMs when in neutral and moving - Manual transmission

nothing special to re-learn, just drive normally. may be a little rough at first but will smooth out as the ecu re-learns adaptive values. shifting rpm hold is a new-ish feature on some models. i know ...

2005 WRX Idle RPM Increasing in Traffic

If your car has a map sensor and developed an air leak that would explain the rising RPMs. In a car with a map sensor the ECU will interpret the additional air flow from a vacuum leak as an increased ...

engine rpm stay far higher than idle when hot

The actual problem was the idle mixture. The screws were not evenly set, and the overall setup was wrong, almost fully closed, while being recommended around -3.5 turns. The problem is now solved, I ...

engine rpm stay far higher than idle when hot

You definitely have to do some checking to come up with an accurate solution. The first thing I’d do is check the cables. As noted, it does sound like something is causing the throttle to stay stuck ...

Renault Clio 2002 high idling on startup

Fuel injected motors have a fuel map in their ECU- quite literally an X-Y grid of ratios of fuel to air that will be fed to the engine. On one axis is throttle position, the other, engine RPM. Those ...
