Slight miss when I start
Hi my opel gamma 2011 had a miss. Tested
coil pack and plugs all ok. Redid the head. In
the morning it starts normal. If I start it
about an hour after use it misses for about 3
secs and stops. Checked software all ok.
Check your distributor cap and rotor too, it might have micro cracks in it that are being affected by heat. Then check injectors, use something like a noid light to check them to make sure the injector pulse is good.
