Rough jerk motion on reacceleration around 50mph
Only happens with following sequence:
Accelerate up to 50's mph, let off accelerator, then re-accelerate..especially on an incline. Get a rough jerk motion until I either let off the accelerator or accelerate hard through it. It doesn't seem to occur when the Overdrive is on. No codes are thrown.
Been to two shops, one a general shop to diag the engine and to tranny shop but neither was sure. I guess I'll have to go to the dealer but I was curious what others think of the problem.

Yep, it was the coils. Once I took it to the dealer they knew what it was but they hooked it up to their laptop while we took it for a spin anyway. Showed it dropping several different ones badly and couple more not quite so bad so I just replaced all of them. Took care of it.
