Hi everyone new to the forum, just picked up an 06 5.4L f150. did a couple searches here and online. Nothing seems to match my issue.
I'm getting a p0171 (bank 1 lean), checked every vacuum line I can find, and sprayed carb cleaner all over the place no change. Cleaned the maf and throttle body.
I have a video of wats happening (no idea how to post it). It only once it's warmed up does the idle get ****ty. By the odd thing is it gets worse if you try to hold 1000rpmish. But like seen in the video of u give it a kick it'll return to just a rough idle!
Any help would be great!!
