Hi all I have the above vehicle chassis no- WDB2903422F047435 With an apparent miss fire.Engine revs up fine but is very lumpy on idle,almost like its down on a cyl.Cleared all codes and ran the engine the following codes returned P2029 Mixt Format Self Adapt/P201B Miss Fire cyl 2 Fuel Deficiency/P201B Miss Fire cyl 3 Fuel Deficiency/P201B Miss Fire cyl 4 Fuel Deficiency.Replaced Air Flow Meter vehicle ran worse (but it wasn,t a genuine meter) so i refit the original and it ran much the same as in the beginning.I tried new coils and plugs but to no avail.The engine idles for all the world like a car from the old days with the choke stuck on.And help would be greatly appreciated as its wrecking my head at this stage.Thanks in advance Dominic casey.PS I'm Pretty new to diagnostics but Im learning so please be patient.
