This has the v6 and EFI
When idling it will rev up to a little over 2000rpm then it will drop to around 1750 rpm and it will do this over and over.

Also at 4000 rpm wether in gear or not the engine will start chugging or cutting out if you will.

Full pump seems to be putting out ok fuel filter was changed and just had the injectors changed in the last month.

getting a code 43 self diagnostic test which is Throttle Position Sensor alert.
Will that cause this problem and is there anyway to test the TPS

Thanks Del
