Finally changed the blue sensor....

[Alec]

And its running even worse than before, idles on what sounds like 3 cylinders and produces the loudest bangs I have ever heard from a car exhaust.... Could the idle switch have anything to do with it?

The car revs and idles ok (maybe a bit lower than it should) when the oil temp reads 50+

The Idle control valve buzzes along quite happily aswell so I really aint got the foggiest what else to try

Any ideas guys? Its becoming extremely annoying now

[JC]

have you had it for a good run during all these " fiddling " sessions ?

[Alec]

Not yet Chuff as my heaters dont work so it ices up as I drive. I drove it last week and got it nice n warm, gave it some sh!t on the way home. Got plenty of pull and goes through the revs very quickly indeed but it simply wont idle at all when cold and if it does its on one or two less cylinders than it should be and when you try to gently raise the revs it starts sounding like a fireworks factory is goin up in flames

Yeah man that did pack up a while back so I gave it an over night soak in an ice-cream tub with petrol which seemed to cure the problem nicely, when that went wrong it was just revving randomly, sometimes as high as 3000 and then it would just die and not run for ages.

I should of stuck with mini's lol

so you didnt change it then?? If not its probally given up the goat.

Also running kjet? if you are there is a little valve in the sytem that my mate is having trouble with at the min, its got bent by like 1mm or somthing and it totally f**ks his idle up. His cousin is a kjet specialist and is sorting it for him at the min... i will have a look in my haynes when i get in and try to find the suka!

[Alec]

I dunno cus that does buzz, i'll get it running tomorrow and unplug it to see what happens.

Its a Digi 8valve aswell dude

I dunno whether to turn the idle screw up half a turn aswell

Does the digifant have an idle switch?

Yes.

@SDCC, sounds like your ISV has packed up. If you really want to give it one last ditch spray it with some carb cleaner, otherwise hit up breakers/ebay.

If not the ISV, look at the idle switch. Had a similiar problem on a Passat years ago, the contacts tend to wear away.
