Hay guys,
I had similar problems on my Corsa, replaced the coil packs was hunky dory for just over a year now...... now my car is jerking / shuddering then proceeds to cut out. Have it at the mechanic, have replaced all sparkplugs & leads new crankshaft sensors, (aswell as a whole bunch of other sensors) new fuel pump and even another new coil pack........ & guess what, she is still doing it. If any of you have suggestions please let me know, I am at witts end
