    Hey guys! Ive been gettinig really shitty mileage too! And have doing some research. But Im getting like 12-13 right now! Freaken Bad!!!
    I heard from a dif. forum that someone had the same mileage and it was his Temperature Cooling Sensor. Does anyone know anything about this? Could it be my problem?

    You should get P0125 or P0126 code if that were failing, but yes it would cause poor gas mileage. Basically, the ecu thinks the motor isn't up to temp and adds extra fuel. You should be able to smell "richness" in the exhuast after the vehicle is warmed up if this were the case. I think that you rough idle may be causing the poor MPG though.

    Alright guys. Thanks for input! I'll do plugs and IAC first and see if it helps. I geuss you can only do one thing at a time and see what happens/ trial and error. huh!

    Well I ordered my Plugs today bc my local NAPA didnt have them. I really didnt want to drive everywhere trying to find them and didnt want to deal with the dealer.
    I was ganna change my fuel filter today but decided not to mess with it. Didnt feel like getting gas all over me!:)
    Instead I washed and detailed my truck!:) oh yeah! Looken Good!!!

    Well I changed my plugs yesterday and the rough idle is still there. Today i'll check my IAC and TPS and see if theres anything wrong. I really dont want to take the whole TB off though. Is there any way I can check them without taking it all off?

    Update: well I checked the IAC and the TPS. it seemed fine. But its probably dirty. So I sprayed a bunch of throttle body cleaner down in the IAC let it sit for a couple min. then started it. let it run at 2k rpms for awhile, let it get somewhat warm. then turned it off. then after 10min. I went out there to start it up and it fired right up! seemed to be idleing ok. But im ganna go out and really see how it's idleing. if its still acting up, ill let ya know!
