ms3x bmw m52tub28 dual vanos misfire

Post by boosted e46 »

Running megasquirt ms3x assembled by a professional EFIextra. Timing on cylinder #1 reading correct, coils and injectors tested and correctly wired and in correct order, when car is started on idle it seems to only runs on cylinders #2 and #4 as can remove coil packs on other 4 cylinders without any effect on the engine. Tried different plugs and moved coils to eliminate dead coils all test fine, timing while engine is running also checks out fine, has anyone else encountered this issue? many thanks
