Bouncer Posted September 10, 2013 Share Posted September 10, 2013 Took icv out, clean as a whistle...the gauge behind it's a bit dirty but nothing bad at all, does this mean it's probably knackered Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 10, 2013 Share Posted September 10, 2013 I would check the MAFS always a good place to start with idle problems. Throttle body could be all blacked up but I'm not sure that it's an easy fix unless you know what you are doing but I guess some cleaner sprayed into the intake manifold would do the same job but not as good. Tlag or MD might be able to aid better then that. 02 sensor another thing that could be doing it :( I know these are never easy fixes idle problem's from when I've had them before :( Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted September 10, 2013 Share Posted September 10, 2013 is this on first start up, as mine does it when its cold, howver the slightest tap to the accelerator brings the revs down, I believe its to warm the oil and engine up, mine idles around 1200, if not as Gambit said.

Bip Posted September 10, 2013 Share Posted September 10, 2013 Do you have a dump valve? These can sometimes cause idle issues. With the engine running have a a listen around the induction side post MAF and around the BOV/recirc for a noise like air escaping. It could be something as simple as a split somewhere allowing air in after the MAF which would definitely cause idle issues. 2 Quote Link to comment Share on other sites More sharing options...
Bouncer Posted September 10, 2013 Author Share Posted September 10, 2013 Yea Forge atmospheric, everything seems airtight, maybe not though....I'll check that stuff tomorrow sometime Quote Link to comment Share on other sites More sharing options...
Bip Posted September 10, 2013 Share Posted September 10, 2013 If you still have your original recirc then it might be an idea to refit that just to see if that improves things. If not then you have at least ruled it out. 2 Quote Link to comment Share on other sites More sharing options...

No don't have it, I'll try the spray too, it's jus a pita, they're thirsty enough without high idling using up more !Removed! juice Quote Link to comment Share on other sites More sharing options...

Jonny b Posted September 11, 2013 Share Posted September 11, 2013 Don't know ιts related but mine had s slight fluctuating idle, also a squeak albeit a very slight one! The steering/alternator belt was quite loose, tightened ιt up ɑnd ιts all good! 1 Quote Link to comment Share on other sites More sharing options...
rallyally Posted September 11, 2013 Share Posted September 11, 2013 I had that sqeak too! Same thing... Alternator belt loose! Is that a common prob with scoobys? Cuz my 1st one had same prob too. I thought it was just my bad luck :( Quote Link to comment Share on other sites More sharing options...
Jay762 Posted September 11, 2013 Share Posted September 11, 2013 most cars get that with use / time the alternator belts stretch slightly Quote Link to comment Share on other sites More sharing options...
Jonny b Posted September 11, 2013 Share Posted September 11, 2013 Same with all belts over time! Tis why they need replacing, mine was a new belt done judge before I got ιt just don't think they tensioned ιt quite enough Quote Link to comment Share on other sites More sharing options...
rallyally Posted September 11, 2013 Share Posted September 11, 2013 Ah... Nice one. Guess I didn't use my other cars as much. But they weren't as much fun as the Scooby is. 1 Quote Link to comment Share on other sites More sharing options...

nvr2lt2sk8 Posted September 24, 2013 Share Posted September 24, 2013 Knackered TGV's can give irregular idle, this happened to me.Normally flashes up a CEL though on the dash which you can check out. would get it looked over.Could be something simple like badly gapped plugs though as i know these can also give crappy idle. 1 Quote Link to comment Share on other sites More sharing options...
