Everything is pointing to the VP's brains. Went ahead and got a VP from DAP ordered up, will update when installed. Thanks again for all the thoughts!

issue started with my stock injectors around 110,000. i had a new set of bosch RV275's on the shelf so i put them in. no change.

yes, its my daily driver. doesn't sit for long very often.

Both, misses cold and at operating temp.

Hello all! Ongoing issue with APPS. Truck developed heavy miss between 12 and 1600rpm wether truck is cold or at operating temp. No codes in computer, no CEL. Tested voltage of factory APPS (after trying resetting it) .54-.79, dropped to .51-.59, jumped to 1.02-1.73, dropped 1.51-1.57, jumped 2-2.7 etc. eratic voltage all the way to WOT at 3.81. ok, bad APPS. New timbo APPS installed per instruction, reset everything, started and miss is gone. smooth voltage .68-3.79. drove 1.5 miles and parked for three days. started back up, truck missed and loaped for ten seconds at idle (never happened before). idle cleared up, but same miss is back between 12 and 1600rpm. No CEL, no codes. Tested voltage of new APPS, same as before, dropping and jumping at same volts. Any ideas on what to check next? Thanks! oh, its got 116,000 miles. The VP was changed at 54,000.
