Did you pull the codes yet? that will tell you exactly whats up, go to autozone or advanced auto parts

defiance

codes? the only code i had was for bad tps which is replaced and the check engine light is gone.

As far as fuel filter and fuel injectors go, i replaced the fuel filter and used sea foam to clean the whole engine out. But the problem is still there, im about to clean the TB to see if that helps

PS. Does anyone have any idea why the idling gets MUCH worse when i turn on the AC?

The AC draws on the engine, so if you are having idle issues that would be why it gets worse when you turn it on.
