2010 F150 5.4 issues. Truck has mods, tune, eforce blower, headers, airbox. The idle just rolls up and down 1500 to 500 to 1100 then acts like it wants to die and sometimes it does or revs back up.
Have changed throttle body's/maf/reset pcm. The tune from edelbrock and the other company we had make one does the same thing. Checked for vacumn leaks etc nothing there. No codes either. Any ideas of what we could look for? Thank you for the board! Sean
