Hello; I’m still crazy My Cadillac SRX 4.6 V8 2007 has misignition on cylinder 1 but only in idle from 1100 u/min it is gone. (Look with a diagnostic device number of misignitions). In cold condition it runs really nice… as soon as the warm gets, it gets better.. But it does not disappear completely. It was made: spark plugs, ignition coils complete and injection valves crosswise swaps no success. Compression on all 8 cylinders super and evenly +-0.3 Bar mileage 143 tkm Has anyone ever had the same ? Love greetings
