Thank you so much! Very helpful. I have a ford mondeo duratec HE. I just replaced all 16 valves and other things, but since then the engine has been stalling especially in the congestion. I am suspecting IAC but not really sure. Any advise? Thanks again.

Hey, my 2009 Mondeo has a electronic TB and here is a problem when the engine is cold and I get to a stop: the moment I press the clutch the car imidiately shuts off... Any ideas?

Hi Craig, very useful video and good explanation. Following your instructions I have easily managed to replace the air control valve, but with the new one the rpm doesn’t go lower than 2500. Any idea why? Thank you in advance

Too much air presumably, check the gasket for leaks. Check error codes.

Hi mate, any idea what the numbers on the IAC mean?

I have a 2014 Ford Focus with an annoying intermittent problem. It drops revs to 200 then bounces back up to 1000 on start up engine warm/cold and when driving “ revs drop to around 200 and slows down” have had the aux and timing belt changed already. Any help would be appreciated

How much later versions use different type of throttle body? Is 2006 1.8 92kW throttle body and IACV different from this Mondeo in the video?

They switched to an electronic TB which doesn't need an IACV at some point. It's obvious to look at, if no throttle cable and IACV.

Hello, I have a Ford mondeo titanium x 1.8 tdci 2008, when I drive normally and keep going up the rpms gradually around 2000 rpms in 2nd and 3rd gear start idleling if I keep at 2000 rpm, the car don't stop, it's look like she ask for more acceleration, or is it a sensor, what could be, it's look like a misfire but it's not, recently I change new injectors I blanked the egr valve, fuel just and only from BP as recommended for ford new fuel filter changed and clean the maf sensor new camshaft sensor genuin replaced. What could cause this symptom? thank you.

Could be many things, could be IACV, or throttle position sensor, or something else.

If I rev the engine while idling then let go, it first goes down really low (400/500) rpm before stabilising where it should. It can make pulling away jerky. Also if the cars moving in neutral the rpm fluctuates up and down. Any idea why??

iac is getting old, replace it :) Dont attempt to clean it, or touch the solenoid like this guy did, it will mess the idle ! Just replace it with a new one and dont touch or play with the solenoid !

hello Craig i have a 2005 focus ZX4 Duratec and when i have all the sensors plugged in when ever i drive it the car will rev to redline, occasionally drop very slowly back to idle but as soon as i accelerate it will stick again. I unplugged all the sensors one at a time to see if one was an issue and it finally stopped after i unplugged the MAF sensor down by the airbox. now it runs mostly perfect except for an occasional bogging issue in 1st pulling into traffic. What im trying to figure out is would the computer really stick the throttle open so much that the car will run away on me? ive followed your videos about the TBS and IAC as well.

@CraigsDIY

Have you checked what the throttle valve is actually doing? If it's opening way up for no reason and unplugging the MAF stops it, possibly the MAF is badly clogged up or otherwise faulty such that the engine thinks there's no air coming in. When you unplug it the engine's default 'guess' is better than the bad data, but it won't be efficient. Or, maybe that's misleading, and there's a problem with the TB (can't close properly?) or the accelerator. Just guessing.

@CraigsDIY

Your Focus has an electronic throttle right? in which case my videos on the IACV + manual TB are not quite applicable, although you can definitely pull off the TB and test it / clean it out - look up the proper procedures to reset it and be careful with fingers.

im not sure i have two throttle cables attached unlike yours i48.tinypic.com/f0xfmr.jpg like that the inner throttle cable will keep the throttle open until i turn the car off and it idles normal until i press the gas pedal, it will then go back to sticking at the really high revs.

Ok so it's the same as mine, except you have cruise control and the plastic cover. Take it all apart and check the butterfly valve movement (smooth & free), and the cable(s). The inner one is your cruise control.

I doubt your 2015 car even has an IACV, surely the throttle is electric? Your symptoms are typical of an air leak or other problem in air intake system.

Craig i have the same problem as Kristen with my old iac i didnt had this problem, but since i replaced it with a new aftermarket one, the rpm drops and goed up at stop. Also the car does not idle smooth when it is in second gear and not touching the gas pedal, the rpm drops very low and than after3 seconds its rolling and idling normal but still not smooth. Could this be a problem with the new iac? Or does it needs to be reprogrammed in the ecu. I already did a ecu reset 2 days battery off. My car is a ford focus mk1 1.6 16v 2004 zetec SE

Vacuum (air) leak somewhere after the TB most probably.

I think the main problem is the blue drawers stuck in the intake.

i have a idle problem with 2004 2,0 Mondeo.. its idle 1500 -up to 2500 rpm also vhen drivning it will not go Down to normal idle but keeps go up betwen 1200 - 3000 rpm . i can hear some hissing i supcekt intake gasket but when i spray cleaner /startgas around manifold it doesnt change up or Down but goes to 1200 1500. when i press throtttle it goes to 2000 2500rpm it shows no fail on Scantool... ? do u have a solution maybe..i ask a mechnic, and he doesnt know, hello from denmark

@CraigsDIY

Sounds like a classic vacuum leak. When you open the throttle it will run 'normally' but when closed it cannot idle normally. If you can't find a leak, a likely suspect candidate is the PCV valve hose, they fail frequently, which is behind the intake manifold (between the engine side and the back of the manifold). You really need to take the manifold off to get at it unless you have tiny hands and flexible arms in which case it is theoretically possible to access from the side once air intake hose is removed. (I am going to do a series of intake manifold & PCV videos, but they will be a few weeks from the time of writing).

The original Ford parts are on big crapp !! if you buy a new oem iacv from Ford store it dies within 3 months! Also their Fomoco spark plugs are crap too! buy Ngk laser platinum, and replace parts with a good brand like Ngk or Bosch. Anything is better than the oem ford part.
