95 318ti power/revving issue

[Dukaine]

ok I have a 95 318ti that runs and does fairly well at a idle and when its cold it will go to about 3000rpms and cuts off like it is hitting a rev limiter and once warm it will only do 2500rpms. They car sat not running with a security issue before i got it and fixed the problem. I have already changed the cam sensor and did a complete test of the fuel system which checked out ok. The Tps is my guess and when i tested it i got some different numbers. Like under the sweep test the numbers i got decreased with throttle instead of increasing. But when i disconnet the tps it is a lot doggier but it still has the cut out at 2500rpms. I also tried unhooking the air control plug and hose from intake and tried running it that way without success. I will be changing the tps but my question what else could be causing this because i dont even have a check engine light coming on.
