Weird Idle Problem

[Matt_971]

Hey guys

Other day after driving the Xr6t it developed a weird problem.

Took off nice n gentle to some traffic lights. Stopped and car was idling BAD. sounded like only running on 4cyls.

Give it a rev and revved different too. Took off from lights as cars all around me I couldnt stop and all of a sudden it came good.

I remember a while ago a drive a mates Ba series 1 xr6t ute. As we pulling into his garage it done the same thing but I think his done it worse. tunred key off and started it fine.

Any ideas what this is. is it a recognised problem from ford?

By the way mine is a series 2 xr6t sedan manual.

Cheers

Matt

mate I've had heaps of probs with idling. unless it starts stalling I wouldn't worry.

Could be a couple of things

Dirty throttle body

TPS (if this is problem, should get warning light on dash)

Coils

Mine seems to have come good recently with some mods., but I'm touching wood.

My BF Auto is doing something similar - when taking off from stopped either in first or second it almost dies for a second before accelerating and the idle can be up and down. I'm having a full inspection on Sat so will let you know what the mechanic says.

I had this problem a while ago and it turned out to be the injectors, Ford dealer put some injector flush through it and been sweet as ever since...
