Okay. Just got back from the shop.
Throttle body and position sensor checked-out fine (.96 Voltage). Fuel filter was replaced in February and is good, as expected. In addition, the PCV tube is fine too. The DTCs recorded were '0171' and 0174'. Fuel Trim (Long = -22, Short = -3) As for the Techron cleaner, pending. The Intake Manifold Gasket is now in question.

There's also an elbow for the pcv system behind the throttle body that tends to get pinholes in it and can cause the lean codes....

Hey 88Racing,
I was shown the PCV at the shop. There were no evidence of damage and/or pinholes. Ironically, they too mentioned that I might be asked that question... LOL I didn't hear from PHP today, as scheduled... bummer. Even tried calling multiple times during their posted work hours. Wittingly, I went ahead and completed and submitted the online form without their guidance I was hoping for. I paid for a Gryphon CS with custom 87-91 Octane performance calibrations. Hope to discover what is causing my problems soon. I've read the potential problems that could occur while driving under this condition for prolong periods. NOT GOOD!

Hey 88Racing,
Just wanted to inform you that I had both the Intake Manifold and EGR gaskets replaced yesterday; Intake Manifold gasket had signs of wear. As of today, no 'Check Engine' or rough idle or engine quits... In fact, the truck's performance has returned to normal, if not better. This was a long shot attempt that paid off!!!  I also took your advise and added Techron Complete to the fuel tank this morning. woot... woot...
