at Wide Open Trottle it bogs really bad like flipping a switch on and off fast. But if let the gas go alittle bit up it than goes normal. i'm fluxuatin at idle too so i'm guessing its my TPS. what ya think?

 

no cel?

 

i got the CEL but its the Intake Air Temp sensor code. That cant be the reason though. Can it?

 

Well, the IAT is one of the sensors related to determining A/F mixture. It could indeed be the culprit.

 

Agreed, if the code is throwing that, then that is most likely your culprit. As Eran stated, aside from the O2 sensor, the IAT is a very big decision making piece of equipment when it comes down to air and fuel mixture. First check to make sure the plug and wires are good, then make sure you're getting some kind of voltage to it. If you have both of those, time for a new IAT. Good luck !
