Good evening Scotty,

I have a 2013 Lincoln MKZ 3.7 with 145,400 miles. This past Sunday night after work, I started up my car and noticed that it was running a little rough. I have a scan tool and so I pulled the codes and initially the only code that popped up was P0017-bank 1 sensor B. I was leaving work and had no other way to get home, so I started driving home and then I noticed the check engine light flashing. I ran the scanner again while I was driving and it came back with misfires in cylinders 1,2 and 3... What do you think the problem be? All the searches I came up with on Google say that it's possible that an oil change could resolve the P0017 code. What do you think of that? I'm pretty good at changing my oil on time, although this time I was past due for one by about 1,000 miles... I drive 400 miles a week just to get to and from work, so I'm on top of my oil changes. Except for this most recent one of course.
