search my friend.
A hose popped off from behind the throttle body...you have to feel back there and put the hose back on. I zip tied mine, it kept coming off and the stupid code kept coming back on.

Malik, yes that was me, sucked ***! But its all fixed now besides that I broke my ABS sensor while fixeing the TC, so that supposed to get in tomorrow and then as soon as I find this little problem, it will be all fixed!

But I cant find the hose you are all talking about! does anyone have a picture of it, of where to feel for it at because it fealt like everything is connected but i dont know for sure! I havent messed with anything behind the engine yet, so im not sure what to feel for!

Thanks!

you have to get your arm behind the strut bar and down...just below the tb/intake manifold...if you take off the strut bar it's much easier to find
