2013 F-150 5.0 running rough
2013 F-150 5.0L 2WD
Got a CEL and took it to parts store and their OBDII reader said cyl # 7 misfire. Truck seemed to run fine and it went away pretty quickly, so I just disregarded it.
About 3 weeks later another CEL light came on, but again it was dx'ed as cyl #7 misfire, went away pretty quickly, but I replaced the plugs anyway because of the mileage. Motorcraft factory replacements gapped to .51.
I went ahead and replaced the coil anyway about a week later and noticed my gas mileage starting to go down, about 1 1/2-2 MPG. Checked the air filter seemed to be fine with no excessive dirt build-up so I just blew it out with the compressor.
I had a brain fart and took throttle body off and cleaned it thinking it was the MAS. In my defense, it looked strikingly similar to the MAS on my wife's Escape that I've had to replace a couple of times. I didn't replace the gasket because I didn't have one.
I can't remember exactly when it appeared but the engine seemed to be running rough when in P or N, but if I have it in D with my foot on the brake, I can't sense it running rough, nor can I detect it running rough when driving.
Today, I gapped the plugs down to .49 and cleaned the real MAS, but still feel the rough idle. Should I replace the throttle body gasket to make sure I don't have a air leak? MPG is still down abnout 1 1/2-2 MPG.
I really don't want to have to take it to the dealership, any thoughts on what else I need to check?
I've considered pulling the old coil back on just to make sure I possibly didn't get a defective coil. All replacement parts have been factory Motorcraft replacements.
Any help or suggestions will be greatly appreciated
