Another idle issues thread.

Yeah definitely change blue temp sensor

[Waspy]

Yep, changed that a couple of months ago. Made no difference to anything. And yep, it was an official VW one.

Tried turning screw on maf air box?turned mine a couple of turns and idles spot on now

[Waspy]

Nope, I havnt tried that. Its not the idle that I am worried about though, it is the cutting out when I drop the revs too quickly.

Oh, coming back to the blue temp sender. I installed it, but I have seen talk about having to "re-set" it or something after the install. Anyone know anything about that?

This is turning into a serious trouble shoiting thread! Like I say, running out of things to try!

The reset is rev it past 3k half a dozen times I think,have you altered idle screw on throttle body?

Ahh, well I did that. EDIT: Actually, not I didn't. I remember now. Every time I unplugged the Blue temp sender to do the reset the car died. So I couldn't do it.

Nope to the idle screw. I havnt touched any setting screws. Thats just for setting the idle though, right?

To be honest mate I would be trying anything to get it drivable,tinker around it can all be reset back as long as you remember how far you've altered them.my revs were all over the place and I swapped temp sensor tried cleaning ISV and cleaning throttle body with no joy so I was pissed off with it one day and tinkered with idle screw and maf screw and it's great now

You are right, I will give it a try. My only reluctance is because it was fine before, with all screws exactly as they are, and now its not fine. So Changing setting is just going to be hiding the real issue. But I will have a play and see.

Good luck and keep us informed

The maf screw is the fuel mix. I wouldn't f**k around with it. If you have a gun check your timing and if you have a friendly garage that will check your co for free during lunch. It should go rough but shouldn't stall when unplugged.

Another thing, is the engine modified in any way, because mine is the timing both static and ignition is set differently to factory settings. If not set up like this the engine would stall if the sender was unplugged.
