hope someone can help I recently acquired a Vauxall/opel corsa with the engine management light constantly on. its a 2000 1.0 12V The symtoms are: WHen cold it starts fine and for the first 2 minutes or so if i dont press the accelerator will tick over (about 850rpm) fine. then it starts to tick over erratically, going from 850 to 1000 and back to 850 and so on. When i go to take off the engine is very lumpy at low revs (like it missing)but accelerates ok.Moving along in slow traffic the ride is very choppy so i have to keep the revs high to get anywhere. Anytime i pull back on the trottle at cruising speed there is a dramatic reduction in power. Then after about 10 minutes or so of driving or when the temp needle reached normal op. temp , it just dies. It will not start again untill it is fully cooled down. Could this be temp related or is it just some fail safe thingy kicking in. Also, i noticed that when i turn the ignition off, the engine kinda runs on for a fraction of a second before it stops. Is there a connection here. Does any of this make any sense or will i have a better stab at trying to explain Im a fairly competent (mechanical)Diy'er but these engine electronics do have me baffelled. Thanks for your help
