Hey all needing some help. I recently purchased a 04 f150 5.4 xlt supercab and I took it through the drive through at sonic and it just plain died. It did it again at a stoplight seems like it idles rough. It runs good on highway. I hooked up the OBD and I got an error code of running lean in bank 1 and 2. Any ideas? Thanks in advance. My name is James by the way. Thanks again Tap Tap
Can't help ya man but just wanted to say welcome to the forum I'm sure someone with more knowledge that me will chime in before too long.
Welcome. This sounds like a problem I had a few times with my old f150. When coming to a stop the rpms would just fall untill the truck finally died. It would start right back up and drive untill i had to stop again. It was the throttle position sensor once replaced it and problem stopped untill a year or so later when it was the fly by wire system on the side of the throttle body itself. But no one just sells the computer part to replace. You have to get a whole new throttle body with it already on there. I ended up having to go to ford and order a new one.
Yup tps sensor is real easy to change here is what you're looking for invade you need something to visualize. 04 2004 Ford F150 Throttle Position Sensor - Fuel Injection - Delphi, Motorcraft, Standard Motor Products - PartsGeek
You're gonna have to remove some plastic engine covers an a few things to get to it most likely but other than that it's two little bolts an plug an play
