jrn1919 Posted March 16, 2015 Author Share Posted March 16, 2015 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 Quote Link to comment Share on other sites More sharing options...
matthewluhman Posted March 16, 2015 Share Posted March 16, 2015 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.

matthewluhman Posted March 16, 2015 Share Posted March 16, 2015 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 Quote Link to comment Share on other sites More sharing options...
jrn1919 Posted March 19, 2015 Author Share Posted March 19, 2015 still the same running ,same report , what does this mean please Quote Link to comment Share on other sites More sharing options...
matthewluhman Posted March 19, 2015 Share Posted March 19, 2015 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. Quote Link to comment Share on other sites More sharing options...
