I have a misfire code on cylinder 2. Would a lifter being bad give that cose

What is your question?

I have a misfire code on cylinder 2. Mechanic ran a smoke test on the car and determined it to be a bad lifter. Would this give a misfire code or cause a rough idle.

What makes this problem better or worse?

Runs good after about 55mph

How long has your 2003 Lincoln LS had this problem?

Since we bought it. 2 weeks
