I stll say just plug into the OBD data link and see whats going on there.
If it won't run pas 2300 even in neutral and act's like it has a rev limiter I would suspect something in the computer system. Does it pull had in gear to 2300? If it does then you should easily rev pas 2300 in neutral.
I'm afraid I'm going to side with CJ on this. If it acts like it's got a governor on it (and it sure sounds like that's how it's acting), the computer really gets suspect. I dunno of any fuel or ignition issue (assuming normal parts) that'd let it run & drive normally until it hit 2.3K & then just not let it go higher.
Onliest other thing that springs to mind is... how confident are we in the tach? Is it possibly actually redlining near 5K but reading 2.3K on the tach? Computer may have a built-in regulator to enforce redline. If the tach's OK, then the computer may be double-reading (malfunction) and thinking it's actually at 4600... and possibly governing the speed there.
