Title: Idling issue 1.8t
Post by: thatwillis on 13 March 2011, 19:57
Hey guys and girls.

Today i started my car (1.8t) after taking a short trip to halfrauds and when i started her up she reved up normally then dropped well past normal idling speed and cut out. I tried again and the same happened. Gave it a rest and tried again. Reving a bit until she eventually idled normally. This has happened once or twice before and is starting to worry me. Has anyone got any ideas? It does seem to be after i've driven a short way and it hasn't come up to temperature. I do need to fit a new thermostat (temperature drops randomly when driving) but shouldn't have anything to do with it.

Any ideas? Ive heard things about needing a new dump valve. Even tho mine was replaced last year.

Cheers
James

I got my code reader today... no codes at all. Which i spose is a good thing. But doesn't help me sort out the problem  :angry:

Any amazing ideas worth checking? Recon having a dodgy thermostat isn't helping things?

Yeah i tried that and i still had issues with the temperature warning light coming on on cold morning.. So i took the temp sender back and got a thermostat but haven't got round to replacing it as it looks like a b!tch to get to.

Check your breather hoses that they haven't split. On my agu the culprit was the s shape pipe which is located behind the dipstick going into the bottom of the intake manifold.

So i replaced the thermostat today argh that bottom bolt is a bugger to get to without a good socket set. (which i left at work)

Gonna take her for a spin and see if she gets to temperature.

Any ideas? Battery light is up on dash.

yeah i tried that  :cry: all properly in place all clean connections. The small nut that holds the thick earth cable onto the alternator is just holding the wire isnt it? (Not the main nut that hold the earth on.)
