Any advice for this ppl? Ive searched and read every thread on the subject but cant solve the problem. Cars fine after a 5min drive but untill then as soon as you take foot off for junction it stalls but only at night when the temp dropped a little but I know its gonna be a biatch in the winter. Ive just changed plugs and air filter tonight and its much worse,stalls, then after the revs drop to to about 400 then bounce back up.
Last week I changed the blue temp sender for genuine vw, cleand out isv? valve for checked it was buzzing and cleaned with carb cleaner but wasnt gunked at all, checked for vacumm leaks checked the wires underneath the injection unit and that it clicks..Its really only when cold that the problem lies. Im thinking possibly the warm air inlet in air flow meter, does that sound feasable or any other ideas what could be wrong or where to look?

i had similar problem and turned out to be timing and fuel mixture
-
Just been having another read throught the forum and this problems comes up quite a bit it seems :rolleyes:
I s`ppose I need to check the timing and co mixture (where can I find one of these?) as per rubjonnys very usefull help guide. Just gotta build me confidence up before messing with anything I wish I hadnt..
-
This one does come up a lot!
Sounds like you have checked all the usual culprits though.
Is it a problem that's developed since you got the car or one that it's always had?
Either way setting up as per RubJ's guide is the most sensible next step.
-
Only had the car about a month but the idle has always seemed to drop to around 600 then pops back to 850-900. Ive only drove it a few times at night and each time its stalled in the same spot (roundabaout). I though maybe if I treated it to a few new bits it may behave itself..how wrong.Just taken the air filter back off and put the old plugs in cos it got worse and until I can get round to sorting he problem I dont need it worse than it was..
-
WUR?
-
I don't think a Digi has a WUR :undecided:
If you've only just got it and have checked all the bits you listed i would definately get it timed and set up as per Jonnys guide so you know the basics are sorted and then go from there.
-

oopsy daisy!
-
Something I touched last night has made it worse :cry:
Its stalling all the time and revs are dropping more..oops
put plugs and air filter back in and that was that
any ideas?
-
Well I would have thought the plugs shouldn't have affected anything unless your HT leads are dodgy. Can you have a check in the dark and make sure there is no visible arcing from any of the plug wires and dizzy?
My guess is an air leak from a split pipe that you disturbed when changing the filter. It's possible there is a crack/split that opens up when the pipe is bent in a particular way and not really visible.
Either that or the MAF has a problem, again that might have been disturbed when the air filter was changed.
Might also be worth chasing the wires from the throttle switch, MAF and temp sensors back to make sure there is no splits further up the wire.
Good luck!

my digi 8v doesnt stall but evertime u come to a stop, the revs dip to around 600 rpm, and then "bounce" back to 900rpm/idle speed as if an anti stall is kicking it? ill start going through the various threads about it and see what i discover :smiley: :laugh:
-

I opened up the air filter housing when the car was still running and the maf was making a sort of buzzing whining noise is this normal?
I also moved the hot air flap maunaly but I dont think thats the problem cos I sucked the vacumm tube and the flap moved so I thinks thats ok
cheers for all your advice ppl..week off work next week so I know what i`ll be doing :rolleyes:
-
Not sure about the whining! Mine seems to make a low droneing sound but it's hard to tell with the exhaust rumbling, alternator bearing grumbling and the tappets rattling! :laugh:
I can't imagine the hot air flap is the problem, I had a K&N induction thingy on mine so no airbox or warm air flap and even then had no cold start problems.
-
All sorted :grin:
Been busy on the car this weekend but theres only 3 things that I did which solved the problem. 1st was tighten the power steering belt properly ( f**king adjuster bolt snapped on me which took a few mins to sort) which Im sure didnt solve the idling problem
2nd was took the inlet hose off and blow a couple of squirts of carb cleaner down the main unit. 3rd was tighten up the inlet hose jubilee clip extra tight
Now ticking over sweet and a pleasure to drive
Compression checked which told me the rings were good
Timing now checked
Oil flushed and renewed, new filter
New air filter
New plugs
But ive still got a problem with smoking and its got worse since someone (not me) tried to help and adjusted the co screw. Next job is to sort that out using rubjonnys thread.
Im deff finding my way round the car now which will help with future problems of which im sure there will be :evil:
-
Nice one, glad you got it sorted! :smiley:
-
Oops, missus just reported it cut out on twice :rolleyes:
new thread for nw problem :cry:
-
Cleaned my throttle body 3 or 4 times today and its alot better coming down the revs, the smaller of the 2 throttle butterflys was really cruddy, i think this the is flap that does idle or very little acceleration? as i operated the throttle the little one moved open before the larger one?
-
Yeah Dolly..cleaned mine out again and I think (touch wood) it may be ok again..hasnt died out anyways
I think the larger butterfly is for the twin choke and only opens at higher revs
may be completely wrong as I aint know mechanic but thats what I would imagine anyways..
-
mine does this too (only at night) but i also have an intermittent problem getting her to start again, struggles to turn over and can take anything up to 8 attempts to get her to go?? :cry:
-
ive orderd a new blue temp sensor, after reading threads it appears this little baby can cause under/overfueling when faulty.. just making it run crapy bascially so for £12 ish and a new o-ring i thought what the hell. also bought a couple of the engine breathers from the flying saucer thing as they had collasped, again only a few quid.
-
I'd replace all the vac hoses, and dont forget the blanked off one round the back of the throttle body, then check the idle switch with a multimeter to verify that it is actually working :) The wires to the throttle switch plug are round the back and they often snap! Yuo should get 5v between the pins on the engine side, and on the throttle body you should see it pass current when throttle shut, stop when throttle opened a bit, then pass current again when throttle is wide open :)
As for smoke I had this and it was the stem seals, would only be noticable when the engine got realy hot.
