Hello everyone I have a 2012 5.7 and have recently had problems that i can't seem to find anywhere else. My tachometer started rising and falling normally but I noticed it started to go down at a lower RPM then it should and stayed there unless I gave it gas then it would return to normal for a couple seconds. I then started to notice that sometimes my speedometer would tick in 2mph intervals every now and then until restarted and the engine seems to stutter when going up hill but would stop if you give it gas. My check 4x4,abs,and traction control lights have come on again after having a repair that I was told was just a abs sensor. Sorry about the long post thanks for any help.
