Follow-up: Ford's diagnosis was a bad connector to the TCBP sensor, a sensor I had thought was one of 3 "MAP" sensors, this one located on the intake piping just before the throttle body. They wanted $450 for the repair; instead I bought the pigtail connector at the parts desk for $50 and soldered it in myself. So far, rock solid, no shudder. Fingers crossed it stays this way!

i had a shudder after I changed the coil packs and I discovered that it messed up when I disconnected the battery to clean all the corrosion around the posts. I had to reprogram the computer. I found the steps on this forum and so far its been working fine.. I had a shudder in 3rd and 6th gear around 1800-2100 rpm.. after I followed the sequence it went away.

Keep in mind that another way to shudder proof your ecoboost is 30k mile spark plug change intervals and maintaining a .030 gap. Plus, the intercooler weep hole prevents any condensation induced misfire.

I just changed plugs on my 2010 5.4 and gasped them at .041 did I miss something? .030?
