2012 Ram with 5.7 hemi 130K mi. Replaced cam and lifters, had heads redone, new gaskets, reset timing chain(was top dead center), checked all push rods after installing rocker rails. Tried to start engine...would not start then only would run at 2000 rpm or above then die. Checked intake no vacuum leaks, now wondering if the MDS system has anything to do with this? or is it programming? have done and redone and checked everything...just stumped. Anyone have any ideas?
