Still have this fault :-( Car was fine before I got banned, put new battery in and since then it's done it. Everytime I stop or rev the car the revs bounce between 200rpm and normal idle it bounces about 3 or 4 times before settling at normal tickover. It often dies mid manouver which requires a restart and usually dies again as soon as I dip the clutch again. Parking etc is becoming a total pig. Car is also stinking of fuel drives with lurches on light throttle and even being very gentle I'm not getting 30mpg average.
It was suggested I have an airleak but this has been ruled out after a thorough check of the entire boost and vacume system.
Help as I'm close to torching the Damn thing and buying an Astra
