I just this minute changed the grease and nouns filter on my 2005 F-150 4.2L. Now it runs rough.?

It seems to have throttle fill & runs rough. I inspected the mass air flow sensor and cleaned it with electrical contact solution. I presently have an engine light & a wrench lit up within the dash. Does anyone have any planning before I go win a code diagnosis. I just
changed the oil & filter, has to be simple right?

Car heat sustain?

Those are easier said than done to screw up, yes it's an easy vehicle to work on.
DO NOT earnings for a code reading. Get it done at a reputable shop or get your code read (a) an auto parts store that has an "OBDII" code reader. It sounds approaching a coincidence.
NOTE: The dipsticks on those are miscalibrated & Owner's manuals wrong. It says 6.5qts grease on an oil & filter change. NO. 6qts & no more. It's full when it read in the middle of the reader on the dipstick.
The above info is correct! I thought is would be mass air flow sensor but you said you checked that!
