Last night on my way home from helping a fellow member remove and strip his engine from his GTT.
I ran in to my own problems on the M25 all of a sudden my Z20LET engined Zafira warning light came on the car then sounded like it was running on 3 cylinders. I am not to good with these modern engines but I think it could be a coil stick or pack failure, it wasn't very light by the time I got home so no chance to have a look will be hopefully be fixing over the weekend.
The temp gauge was fine, and no smoke or anything from the engine or exhaust, no leaks when checked, I will check sparkies any other suggestions?
