At 154k I'm on a third set of injectors. Most recent issue was loss of oil pressure. Mechanic replaced IPR, IPC, Stand pipes and a fitting on the HPOP(the cause of oil pressure loss). While he had it apart, also did an EGR delete.
Ran great for 4 days and then started noticing a bit of rough idle intermittently.
The problem has progressed. He rode w/ me with scan tool attached and only errors are mass airflow and non correlating intake air temp. The problem comes and goes, but seems to be worse when warm. Any thoughts would be appreciated!

 

Just a thought... VGT sticking? Probably wouldn't cause idling issues but one never knows!
