You may laugh, but every time I've changed my fuel filter my car idles smoother...
I changed mine like a month ago..as i said I just dont know what it is and I cant stop at a redlight normally without seeing my car jitter to stall then to normal then dip down to stall..i dont know what to do

With all that stuff replaced it could be vacuum leak. Would that have something to do with the codes you are showing for the 2 upper O2's?

if the codes are for lean banks then it has to do with a leak after the MAF ... covered before, start listening for leaks

these were my codes
P1151 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 2.
P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1.
P1120 Throttle Position Sensor out of range.
now the TPS I dont know much because I didnt play around with it, its brand new and as it was i put it on without playing with it..Car started up but the idle thing is still messed up..
so if the there is a leak after the MAF, that would make it around my inlet pipe then right?

No...it would/could be anywhere after your MAF (inlet pipe, TB gasket, UIM/LIM gaskets, IAC gaskets, brake booster lines not seated all the way). You're gonna have to get some carb cleaner and start spraying around the different areas while the car is running and see if it stumbles...that'll be your leak.
BTW...you did get the MIL's on right? And they were installed correctly right?

I understand that...as I just did as well...but that doesn't mean that some of them didn't get displaced during assembly bro. Gotta start somewhere and eliminate the eliminatebles...right?
