I finally took the throttle body apart and the guy NEVER replaced/rebuilt the regulator diaphragm. Did you get it off line? I purchased several 'rebuilt' throttle bodies a few years ago from an eBay seller but had seen issues you are currently having. Another thing I would double check is the rebuilt throttle body. Hey, These guys are offering some great advice. Using the reader with a laptop you can get documented engine output while your driving down the road. Just a random link you can make your own cable (I did) or buy one for less elsewhere. Or you could buy an ALDL cable, and down load a free program to read your engine's performance Turn key on, the engine light will flash 12 three times then any codes if stored. With the key off, install a paper clip between A (ground) and B (diagnostic terminal) in the ALDL ((look closely they will be stamped A, B, first two slots, top row right). Locate the Assembly Line Diagnostic Link (ALDL) typically under the dash below the steering wheel. Once the above is within specs check for any ECM codes Ignition (make for you have 6v at the coil with key on) Ignition wires (check each wire for the correct specs)

The best way is to start from the beginning with the process of elimination, it's the only way I know how to do it. If you call Howell they won't have any magic answers for you, nor will I.

You have a choice, do the work yourself, or pay someone else to do it for you. You can trouble shoot any FI sensor by doing a search on the net. All the sensors can be tested, even the O2 using a meter and propane torch. I always test any suspect sensor or component to confirm it's bad before I replace it this way I not wasting my money without solving the problem.
