OK - it may be a boring car (Astra 1.6i Caravan CD, whopping 71 bhp) but it's taxing my brain. If I take my foot off the throttle for any amount of time and then want to accelerate the car hesitates before coming back with sometimes just a jerk(!) and sometimes a real kangarooing misfire. Also, at low speeds, when slowing down (such as coming up to traffic lights) when I push the clutch in to stop, the motor justs cuts out. No warning on the self-diagnosis system, and, of course, sometimes (but only sometimes) there's no problem. Any ideas??
