Hi there
My 1990 8v digi will not idle. The car starts ok if it is not too cold and runs ok for 2-3 mins. Then it just idles progressively worse until it refuses to idle at all. It runs quite well and feels strong but this is driving me potty. Have done plugs, dizzzy cap, rotor arm, ht leads but to no avail. Does anyone know what this is?
Thanks
Alan

Maybe its hungry....?.....................!
:tongue:
seriously though, is it from cold only, how about when its warm?
mine was a pain with the idle when i got it and after a week i found one of the vacuum hoses from airbox was split, changed it and reset the idle - sorted.

Hi Chugadub
It idles fairly well for the first 2-3 mins after starting from cold once it is warm it just will not idle. I can prevent the stall with a bit of jiggery pokery with the throttle pedal but it idles very poorly lumpy and spluttery.
Sorry about the decription

1st thing to do is replace the blue temp sender, about £10ish from VW :)
-
is that the blue temperature sender that sits on the 5th injector, i got told by GSF that was about 60 quid the other day................luckily i walked away
-
There is no 5th injector on a 8v Digi? Either way it isn't the same thing if they want £60 for it :)
-
when i replace the cylinder head on my wifes digi i forgot to plug in the airflow meter and it did the same as you are saying so i would check the connections to the air flow meter or even change it for one from a scrappy and see if it sorts it.

Hi there
Thanks for your replies. It is a pain in the arse. I have unplugged various sensors and the one which does not make a difference is the one in front of the blue temp sender, does anyone know what this does?
Cheers

The black one? Thats for your temp gauge so I wouldn't worry if nothing happens when you unplug it :)

Cheers rj :embarassed:
I also meant to add that it is quite a poor starter. I put in new battery so it cranks over really well but it is really reluctant to fire up. When it finally does the starter seems to turn over really slowly just before the car starts then it will start and stop fine until the next day????Pisser

So far as your problems with it starting go, obvious place to start looking (assuming you haven't already) is the spark plugs, make sure the gap is correct.

Hi there
fair point.
I put in new plugs but did not check the gap.
Could be something in that
Thanks

it sounds like it just needs setting up properly by someone who knows what they're talking about. you need to get the timing set up, then check for any vacuum leaks and any damage around the crankcase breather bung in the rocker cover. then re-set the ecu and go from there. but the blue temp sender causes more problems than you'd imagine!
-
How did you know that I know nothing? :laugh:
I have thought about that but hoped that I could find the problem. I suspect that timing may be out but should it go so fast if the timing was f**ked?
Does anyone know of a good and cheap digi fixer in South/Central Scotland?
Cheers
Alan
