Another idle issues thread.

[Waspy]

Thanks, I will check the timing at the weekend.

As far as I am aware, the engine is not modified (as in I havnt touched it). But at some point it has had a chavvy owner, since it has a redbull ca covering the starter (what) and a nice big K&N filter. But I am pretty such there are no serious mods.

Im not sure I follow the last bit of yopur post, are you saying it will stall when unplugged if the ignition is set up differently to stock?

[Sgt_Lemon]

If the ignition timing isn't set up right the car can stall when the blue temp sender is unplugged.

[Waspy]

Got ya.

Yeah I'll do the timing tomorrow!

[Waspy]

Right lads.

I can't do my timing as my strobe isn't playing ball.

I have had a play with both the CO screw and the idle screw. And by a play I mean I screwed them as far as they would go in both direction and then returned them to where they were. At no point did the engine change note, or idle differently or anything. This worries me, it feels like there should have been at least an idle change since I was playing with the idle screw!

Thoughts?

[Sgt_Lemon]

Ignoring the co screw on the maf, your saying the idle didn't move at all when the screw was moved?

[Waspy]

Correct, not a bean.

I actually doubted I had the right screw. But I did.

If it wasn't posing down outside I would make a video.

maybe your isv hose is partially collapsing under the higher engine vacuum when your slowing down???

[Sgt_Lemon]

I would be more inclined to think that the idle switch wasnt function correctly still, that the car doesn't know it should be idling. I'm pulling that theory completely out my arse though.

[Steve_B]

Have you cleaned the idle screw? If the outlet is bunged up turning it won't alter the amount of air coming in. Also, I think the blue temp sensor needs to be unplugged for it to make any difference, as per the set-up guide.

I dont think the blue sensor needs to be unplugged to adjust the idle screw, when I turn mine the revs drop and rise accordingly, also the engine should change when the mfa screw is adjusted...mine goes from smooth to rough.
