disconnected tps?

I recently bought a 97 Tacoma 2.7 reg cab 33 tires problem is I have no power on the high end at all I got plenty of pedal but if I go wot it does nothing at all like it hits a rev limit and now idle is 1900 all the time have done the usual tune up plugs wires air filter fuel filter cleaned may and tb replaced some vac line etc so today I disconnected the tps idle moved a hair and cel came on so I drove the truck with it unhooked and I see no difference at all other than cel is that normal or have I hit on something?
