Okay so for about a month already my truck has been acting up real bad. It started out as it stood in idle at a stop light or whenever it was just idling. The rpms would ride to about 900 instead of the normal 600 it always was at. Then it started getting worser to where now it spits and sputters and wants to die whenever it's idling. But as soon as I give it throttle it goes like nothing but when it's idling it sounds like ****!!! It already has a new IDM a new PCM and new fuel pump(the one that's by the turbo and is a pain the *** to change). I also change the cam position sensor 2 years ago. This issue is something maybe fuel related or some sort of sensor.it only does this at idle. And the truck sputters so bad it shakes like crazy and sometimes even turns off. Then there will be weeks with it not doing it then out of nowhere does it again. Plz help me figure this issue out
