Title: erratic at tick-over
Post by: chimp on 30 March 2008, 18:43
hi chaps, im starting to get problems at start up on me mk4 1.8t. when the engine is cold and i fire her up the tick-over initially goes to 1100 revs which it always used to do but then as it drops down to 750-800rpm she starts to idle roughly, dropping right down to 350-400rpm almost stalling, i have to give her a bit of persuasion with the throttle. when its warm it seems ok. it was serviced in aug 07. any ideas, cheers.
