I have the exact same Fiesta with the 1.4 duratec engine and heres a tip for you guys ,get yourself a spare air box maybe from a breakers yard or keep the one off the car you may of scrapped earlier .Store it away somewhere and the night before you can change the filter at your leisure and simply switch over air boxes ,in my case i have a K and N filter in the car but keep a normal filter as a spare .

Hi should the butterfly valve completely close when u it detached. There is a 2mm gap on mine but closes more if I push it then it Springs back

How did you reset the car after unplugging the sensor

Thanks, I gave the throttle body and MAF sensor a good clean today. My car does start but sometimes takes a second attempt or requires pressing the accelerator to get it to start, will see if this has helped. Which tool do I need to remove/reconnect the hose clips? I was able to get them off but wasn't able to reconnect the clips so have taken them off and fitted standard jubilee clips until I can find the correct tool. Thanks.

Hi mate sorry just see your message, is it the 8v engine as that’s the only one with idle control valve? My advice take your time clean everything thoroughly with carb cleaner and use new gasket for the ICV

Wat do u think the issue was in the end? Idle? Dirt or air filter?

@BugRacer1955

Not 100% but I think there is an air leak somewhere as the engine is over-fuelling

On the reset car will only run if I’m keeping the revs on will not idle itself just stalls. Like yours did in the video. What was your exact reset procedure please while everything’s on and your holding revs turn off ? And how long hold please

Need to do throttle body relearn after doing anything touching the throttle body at all, even just moving the butterfly valve. Search Ford Throttle Body Relearn

My 2005 MK6 fester is idling at 1500 RPM, going up to 2000 if I drive it around for a bit, going to try the throttle body / MAF sensor see if it sorts it. Haven't cleaned it or done anything other than change the oil in 2 years

Hi Jamie can you smell petrol? do you think it’s overfueling? Without seeing it I would start looking for possible air leak, start spray some water over your hoses see if you can see any bubbles...looking for a possible split hose. Go really carefully don’t let water get in your electrics.

it takes the oil fumes of the top of the engine (camshaft and valve stems) by the airfilter back to the engine for burning.Thats why you see i a bit oily.

Actually I don't think what you call the MAF sensor is a MAF sensor, it looks like an air temperature sensor so it can run rich when it's cold to warm the engine faster, like an old choke used to be. And if the TPS is the big bulky type maybe the maf sensor is combined with the tps

If you DISCONNECT your battery leads and touch them together or bridge them for 2 mins (minimum) your car will empty all the residual power from its electrical system and perform a hard reset as soon as the battery is reconnected….the leads MUST be off the car and they MUST be touching each other
