wont tickover !

my '83 gti 1800cc is having difficulti ticking over until the engine has warmed a little.
it also ticks over at around 1100rpm once its been driven and has got to temp.
got any ideas?

There are probably 2 reasons,
1. faulty warm up regulator
2. worn idle screw

The warm up regulator does exactly that, regulates the engine while it is warming up. Mine wouldn't tick over when warming up and a replacement solved the problem.

The 1100rpm could be down to a worn idle screw at the back of the throttle housing under the scuttle panel. I have had problems getting the revs to sit at the recommended 950rpm for 3 years. The problem was solved by replacing the screw that has a rubber washer sunk into it & that tightens in the housing and holds the revs accurately. The part only cost ?10 but it was worth every penny!!

Maybe that helps?

Think Dano's hit the nail on the head there!

also worth checking for any air leaks from cracked hoses etc

Warm up Regulator's arn't cheap though  :cry:

is there any way of testing the Warm up regulator?

Only way I know of is to substitute with a known good one.

Mine had a simelar problem recently, found it to be a mixture of the timing being out, and the fuel mixture being set wrong. Both easily sorted, and car runs wonderfully now.

Don't forget the Auxulliary Air Valve as this will increase revs when the engine is cold and close when warm.

The WUR can only be tested properly by doing the series of system pressure checks.

Oh yeah forgot the timing as well….  ops:
