Spark plug leads are all fine, coils are working.
It seems everything is working as it should be, but the engine is running really rich. The mechanic thinks it could be the inlet manifold and air is escaping through it somewhere making the engine think it is running rich.
Both of us are baffled about what it could be. Even had an endoscope in around the inlet maniforld to check the valves etc.
Would VIS motor failure cause the engine to run rich and misfire?
