Check all the rubber gas lines going to the steel gas lines they maybe collapsing under pressure cutting off gas flow. I know this can happen because it happened to a ford truck that I owed awhile back.

Start at the cat, if you can get it to an exhaust shop, most should check the pressure diff for free...phone around. It may be really restricting exhaust flow. Next, get your hands on an engine scanner that'll read live data, wait till the engine is at normal operating temp (if she'll run that long) and record the short and long term fuel trims and O2 sensor readings. Do this at idle/1500/2500 RPM. Trims should be around "0" at steady RPM and load. The upstream O2 should move up n down in voltage or % depending on which your scanner displays, the downstream should be steady at some voltage around .5 volts...you just don't want it pegged at 0 or 1volt.
