I'm A mechanic by trade and lost when it comes to this problem. The truck spits, sputters ,stalls off idle. 130,000 miles fresh tune up parts. TP voltage smoothe and where it should be. 60 lbs fuel PSI does not change when problem occours. MAF voltages in normal ranges. No vac leak in brake booster.IAC changed with known good one. Upper n lower intake gasket replaced. No vac leaks to evap system or purge solenoid. There is a po1747 code epc high input [eletronic pressure control] and po1451 canister vent fault [canister vent circut pinched off to make sure it was not stuck open, There is some O2 sensor ground codes that I have not addressed yet, problem exists in open loop too.
