My ford f150 is showing a code of lean bank 1 and bank 2 and now it is idling real high. I've changed the MAF sensor and the the idle sensor. I've sprayed wd40 around the intake gaskets and checked for air leaks and haven't found anything. Does anyone have any suggestions?

I have a F150 5.4. I rarely drive it. It only has 80k miles. Drove it and it started to stumble. It felt like the transmission. Had it checked out. Not the transmission. Engine light not on. The engine is smooth at speeds about 70. Some told me it was the EGR so I replaced it. Still stumbling. Does anyone have any idea what could be the problem? Thanks in advance
It sounds like it could be your idle throttle body needs cleaning. Get a can of trottle body cleaner from the auto parts place. Remove the intake filter and trottlebody cover and spray cleaner directly into idle body with truck running. Spray slowely to avoid killing the engine. You don't want to keep restarting the motor. Utube has a good video on how to do this.
