Hello all, I recently had a full service/mot and my timing belt renewed at 40000 mls. as per vauxhall instruction,but ever since the car keeps stalling when Ive come to a stop,not all the time though,also if you sit and listen to the engine you can hear it skip a beat ever so slightly. Thought I had a dodgy plug,not so. It goes through the gears fine and is better than ever on motorways.I had the work done by a family friend who owns the garage. Its been back a few times to try and resolve the problem, i.e. more new plugs/leads,even a new coil,but to no avail. I dont doubt their work regarding re-setting the timing belt etc. ,after all its bread and butter stuff. Its had the full diognostic kit checking it out but came up with no errors every time. I understand an auto is not supposed to stall as the engine management sorts it all out,well this one does. Any guidence much appreciated.
