Well it’s almost a year later and I finally got around to this.I just picked my truck up and notice a little “jerkiness” in the acceleration. I’m gonna try the plugs.
The last Ford I bought was a ‘01 Mustang Gt. The previous owner warned me it would ping on hard acceleration if not ran on premium fuel. I changed out the Bosh spark plugs for factory motorcraft and the problem went away.
I lost the motorcraft plugs I was gonna use. Parts store didn’t have them either. I used NGK’s.
Factory plugs were pretty dirty but didn’t show any wear.
EDIT: I'm at 80k miles.
