When was the last time you replaced the plugs, wires, and dist cap/rotor (1998 is old enough to have these last two I think)? At 200K miles, they should have been replaced about two times by now. Did you replace the 3 sensors you identified because of error codes or were you just going at the problem blind. Even OBDI vehicles like yours create error codes that will help diagnose the problem. Have them read and work from there.

Good evening, the plugs , wires and Coles have been replaced with in the last 6 months . I changed those sensor because that was told to me that those could be the issue. No codes are popping that have anything to deal with the issue I'm having. So I'm not sure what else to do
It sounds like you have exhausted all of the driveway mechanics you could so maybe its time to take it to a reputable shop and let them diagnose and fix your problem. Good luck.

Yes when I changed the throttle position sensor. I cleaned out the throttle body
If it's burning more gas than usual and shifting oddly you could have jumped timing I've been with the same issue and changed everything that you did . Your timing belt probably broke at you and slip try pulling timing belt off buying new one lineup to manufacturer specs and reattach belt
