By reading your post, you have covered most of the bases. The one thing I didn't see on you replaced parts list was the crankshaft position sensor. The knock sensor will retard the timing, but it should run reasonablt well. The CPS, on the other hand, controls injector pulse and spark timing. You may want to take a good look at that. Hope this helps.
