Autodiagnos gives fault code air mass flow meter circuit.Changed meter (although cheap one from EuroCar parts).Erased codes,road test,all good for 3 or 4 miles.Fault returned(idle erratic,kangaroo,loss of power etc)Read codes-same code-fitted another cheap meter,still the same.Tested earths,alt charge rate,air leaks etc.
Testing on the 4 pin plug at meter when connected,5v,0.02v,13.96 v & 2.56v fluctuating to 1.9v all at idle.This to me indicates faulty cheap meters.Any help appreciated.
