Title: 16V engine stalling when cold
Post by: GTI_16V on 18 May 2005, 08:00: Hi, a little bit of help on my (hopefully) minor problem would be appreciated!

When my valver is cold it stalls whenever i stop revving. It normally cuts out when i rev it above 2000rpm then let it drop to idle. If i let the revs drop slowly to idle it seems to fine - it only happens when the revs are dropping a bit faster (i.e. when i rev it then let it drop). Once the car is warmed up it is fine. Any suggestions??

This link has some good advice , the only thing that I would change/add is that the when the 16V s first came out they tended to suffer with idle/stalling problems .

1)Ãƒâ€šÃ‚Â I believe that the ignition should be switched off when disconnecting and connectingÃƒâ€šÃ‚Â the red lead .

2) VW sentÃƒâ€šÃ‚Â updated tuning data which if I remember correctly stated that the idle speed should be adjusted to 1000 +/- 50 rpm instead of the previously stated 950 +/- 50 rpm

3) make sure the throttle cable is not too tight so as not to allow the throttle idle switch to closeÃƒâ€šÃ‚Â .( I had a customer that kept fiddling with the cable adjustmentÃƒâ€šÃ‚Â on his and then wondered why it kept stalling .... the penny eventually dropped ! ....now it idles properly .Ãƒâ€šÃ‚Â

P.S. I also have changed the idle stabilization valves for modified onesÃƒâ€šÃ‚Â ( modded ones had a yellow sticker on them ) but this was back in the 80s so I would imagine they have all been done by now unless some may not have being that it was not a recall as such. :smiley:

Check the Idle Stabilisation controller in the centre console. Find it and disconnect it. If the car does exactly the same thing with or without it - then its boogered.

Find a smashed 16v - theres one a week on the forum and give the owner a fiver for it. If you buy it from VAG - expect it to cost around 120quid.

You're quite right about the control unit behind the center console I completely forgot about that ...long time since having probs with one ... I'm not definite on this but I have a vague recollection that the control units were replaced as well..... way back when... but don't quote me on that :undecided:
