Surging power delivery
I have a 2013 Ford Focus se hatchback 5 speed with about 1600 miles on it. Since I drove it off the lot there have been 2 incidences where the powers delivery seems to surge down. Not quite a misfire but almost a hiccup in delivery I guess you could say. Yesterday in 2nd gear as I was increasing rpms it surged 3 times over a period of about 3-5 seconds. Should I have the PCM reflashed or is this a tuning issue? I've seen some dyno charts on this motor and some seem very choppy through the rpm range.
