Almost Stalling - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Just wanted some help with my AU, pretty common problem I think.

I have an issue of the car losing revs and almost stalling when im idling. This only happens when the air con or demister engages and also under heavy steering whilst driving at really slow speeds. It hasn�t stalled just come close and the car gets a quick shake and then regains the lost revs.

My worry is that in summer when the weather gets alot warmer and the air con is on often it may start dieing on me. Car is stock 4.0L auto.

So how can I stop this from happening?

Thanks All

call into your friendly ford dealer and get them to put the latest calibration in your computer and reset the base idle should fix teh problem

Sounds like a vacuum leak to me.

Check Your Inlet Manifold bolts bet they are all loose

I've got the exact same problem that started just recently except mine's not doing it with the air-con on (then again I haven't checked but I will tomorrow) it's only happening under heavy steering at slow speeds. I got told it could be:

an intake problem
a vaccuum leak
the power steering switch
the ISC and so on...

I'm planning on having all of the above checked and I'll let you know how I go.

(I just read through my service book and the air-con was recalibrated on mine at 50,000k's - that's about 31,000k's ago)

I think mine does the same thing, im just to slack to go see someone about it, drops revs when you hit steering limit while in the car park / stationary, also when you put it in Drive from Park.. or Drive to Reverse.. or any combination for that matter..
Let us know what your problem turns out to be. :)

Cheers

If your car is dropping in revs when demister goes on check your car battery.Apart from that reset the computer.And if that does not work check your tps and idle screw...If you turn the idle screw in too far it screws up the computers ability to meter air at idle...and idles up and down with the power steering being turned too

I had an off idle for a while until I had my throttle body taken off and cleaned up. Since then, all good. No more probs.

Funny you should mention that loxxr6 - I clean the throttle body yesterday & the idle improved dramatically.
