@Engine Nut suggested that the throttle body may be dirty in this thread, but the OP never came back with a result.  I think that's a great suggestion whenever performance seems to suffer.

I suggested maybe looking at the cannon plug in this thread, but the OP never came back with a result.

I would take a close look at connectors and their associated pins to make sure that everything that wants data is getting it reliably.  That many codes seems like the ECM isn't reading sensors correctly.

I'm a believer in clean throttle bodies and clean connectors.  Most of the sensors and electronic parts on these engines are rock solid.  I have long suspected that most issues are caused by crud buildup or oxidation.

@justgary - thx for those links.  Need to find Larry's email address as he seems not to check too frequently here these days.
