Hey everybody, i recently came across a rough idle on my 06 f150 lariat 5.4L. I have cleaned the throttle body, cleaned the MAF sensor, replaced all 8 plugs with motorcraft platinum and just replaced all 8 coils and still have a rough idle as well as when im driving. Does anybody know what else i should check? My check engine light is not coming on either so i dont have a code that it's throwing either.
