Sounds like your generally running rich. Probably just needs new O2 sensors and/or coolant temp sensor, and maybe cleaning the IACV.

I have done o2s an ill get coolant temp tomorrow. And my idle goes up and down when i stop some times. And i have a question. If i cant get my tps within spec does it need to be replaced at full throttle it goes up to 4 but closed it only goes down to .45 when it should be at .4 closed i believe.

The TPS should read 4-5v at full throttle and 0.45v at idle.

Which brand of O2 sensors did you install? And have you checked for codes yet?
