Hi guys, test drove a 2.7 SCREW today. First time driving an EB & overall was very impressed with it & the 21 in general.

HOWEVER, this is a brand new truck and had a shimmy, almost like a miss at idle. Tach didn't budge but it was noticeable. Maybe like a 4 cyl shudder at idle with the ac on, ya know?

Is that normal for these motors?

Edit- noticed in drive (normal drive mode) and in park

Every now and then mine will do it, I always look to the tach but it never moves. I just assume it’s something kicking on or charging up like the auto stop feature.

Mine has a shutter sometimes. One time, bad enough that the tach dropped about 200mpg’s but that’s the only time I’ve noticed it on the tach. I’m gonna see if it continues. If so, I’ll take it to the dealer. If not, I’m just gonna roll with it.

Mine will have an almost unnoticeable shutter when idling with the AC on. Otherwise buttery smooth.

I would say that yes mine does have it, it seems especially noticeable on hot days (so likely when AC is on)

Same as me, If it’s hot out, it will shudder a bit at idle
