About a month ago I was driving and had an obvious misfire for about 30 seconds. I was able to pull off the main road and plug in my bluetooth OBDII scanner and it said I had a cylinder 7 misfire. The misfire soon got better and I drove home fine.
For the next month I had a slight hesitation or stumbling while slowly accelerating with low RPMs, even stalling a few times on slow uphill accelerations. Higher RPMs, harder acceleration, and idling all felt normal.
I was checking everything, but couldn't find the issue. I had replaced the spark plugs only a few months ago with new Motorcraft ones so I assumed they would be fine. Since I had checked many other things already, today I decided to check the plugs. Sure enough, when I got to the cylinder 7 plug, the top strap was missing so it wouldn't have been able to make a spark. I replaced the plug and the car runs great again!
Since the issue is fixed I wanted to share this in case it can help someone else. What surprised me was how little a difference having one less cylinder made and I was not getting any codes or check engine light. While the hesitation was noticeable, but still slight on the slow accelerations, it didn't seem to affect the majority of my driving. Has anyone else experienced something like this?
