[jrn1919]

can anyone explain this to me please in english , or simple mans term

im hopeing this will explain my problem

[matthewluhman]

Whats the problem your having

[jrn1919]

rev`s hanging when changing gear, cutting out 4 times just recently when pulling away ?

or even stationary rev it ,it takes to long to come back to tick over

[matthewluhman]

Rev hang is conmon on modern cars and is due to emission controls. I suspect the cutting out is a different problem all together which may have made the rev hang worse due to the ecu trying to compensate for a faulty component by using a preset safety map. 02 readings like these dont mean much on there own. Go into live data and watch a graph of voltage of the 02 sensor/sensors to make sure thier reading correctly as the voltage should move around during driving.

ok will do,when i get it back , btw this was stationary if it makes a difference

[matthewluhman]

Engines act completely different under load. Its always worth checking the timing hasnt jumped a tooth as its best to start eliminating the basics and working from there

[jrn1919]

still the same running ,same report , what does this mean please

[matthewluhman]

Look at the volt range from min to max it doesnt look correct. Remember elm is only a universal obd2 reader so that reading might not apply to your car.
