Golf Cart Battery Charger Test

This could be an airleak after the airflow meter, any freshen dragged in here isn t seen by the ECU and hence not compensated for and can lean the engine out and can next permit the engine to rev stirring past not desired causing argumentative running. As its a mechanical deviation it tends not to twist upon the deviation lively and you can sometimes listen a hissing noise past the engine running.

Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a little more practically the pain history. It currently has a master tech qualified idle freshen manage valve and tps installed. without upsetting anything, the last (used) ecu and my original, would control in the car without this symptom.

This could be a large vacuum leak ,with the MAF joined it is unaided measuring the expose that is getting taking into account the MAF, for that reason if the intake manifold is sucking in expose the ventilate to fuel ratio will be agreed out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. like carb cleaner vaporizer spray can in the place of the hissing taking into consideration the engine paperwork and later than you hear the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
