How do I fix a problem of engine cutting out when I have air conditioning on and I slow down ?

SOURCE: 2003 Expedition jerking/cutting out.

Had same problem: cutting out at low rpm, jerking, a huge clunk or shudder at higher speed (like transmission was going out), and rough idle. All these symptoms were intermittent.

CHECK THE FUEL FILTER!! Changed the fuel filter and thing runs fine!!

PS mine 2003 expedition has 105k

SOURCE: Revs ''hunt'' on tickover, sometimes revs drop so low car cuts out

Thanks to some advice I have fixed the problem with my Granada. The pipe work from the exhaust manifold to the inlet manifold has a short piece of plastic pipe which needed replacing. This seems to have done the trick.

I would like to thank you for running this site. Without it I would still be re-starting my car each time I stop at a red light!

Your cam position sensor is on it's way out.

Hi I an Vortash there are a few things that can cause this ... Air at the inlet manifold caused by a faulty gasket ?.... Air leak in the Brake servo causing loss of Inlet vacum ( this would be noticeable with the fact that brakes would be a little spongy but not always and sometimes the engine revs increase when you put the brakes on when staionary ) Faulty throttle cable ... faulty throttle sensor .. best way to find out is to have the car checked out on a Krypton tune machine ( or equvalent ) to determine the fault otherwise you could spend out on un nesscasary parts .. at least the machine would pinpoint it for you .. It is always adviseable if you do your own repairs to get hold of a Haynes manual for your vehicle it will tell you all the best ways of treating most of your cars problems cheaply and efficiently hope this helps Regards Vortash

Have you tried checking your throttle positioning sensor. Possible vacuum leak or check for carbon build up in the throttle body not letting the throttle valve shut all the way.
