Surging - Bad fuel injector?

[DRII]

A quick update for me. put the stock plugs in but still had the shuddering and misfires slowly incrementing.  Brought it to the dealer and they spent 3 weeks chasing the misfire counter by replacing plugs/3 new coils and finally escalated to corporate.  Corp had them run some extra tests and they determined it was the torque converter (which I had suggested when I dropped off).  The shudder went away once it was replaced.  Driving the new loaner vehicles gave me the new car bug and I traded my 2011 SHO in on a 2017 MKZ 3.0t AWD on Saturday.  Loving it so far, just need to spend some time researching what I want to mod

Stopped at the drag strip 45 mins after leaving the dealer, only got one pass in, 13.7@102.  I'm guessing a full tank of 87 octane and 41 PSI in the tires didn't help.  Hoping for low 13's stock with some good 93 and playing with tire  pressure.

Nice!

wish Ford had put at least an 8spd transmission in the MKZ and Conti by 2017.

They stuck one in the new Edge ST, disappointed as well that they didn't throw it in on the 3.0 Lincolns.  It was definitely one of the negatives when evaluating my decisions.
