Once throttle is applied again all cylinders begin firig again for full power. That should be plenty to run down the road (truck only). Here's how it goes: Check the exhaust pipe: Fix the holes. You must live somewhere flat, i drive 54 miles on an interstate near pittsburgh, i average 15. That sounds great, until you pluck that imaginary big-block from between the fenders and stick an in-line four in its place. RAM 1500 Hemi owners...MDS or not.

Mine is a trx4 with a 5 speed so i wouldn't get the mileage you got on either truck. Took a week of arguing with Chrysler about oil changes, but they finally stepped up and repaired it. I wish I could lock the MDS in and keep the overdrive from down shifting and use it with a greater throttle input to put the motor in a more efficient BSFC. I have started driving my 2012 in 5th gear mode on the auto stick and it has not dropped the MPG even 1/10th per gallon - no differance at all and smooth as a whistle in straight 8 cyl all the time. I do think that running 89 octane is much preferable during summer months though due to seasonal blends. Started acting up and i diffidently felt it kicking in and out. My hemi liked Mobil 1 0w20 and 89+ octane.

Hey guys--I am the one who started this thread in 2010-2011 with an MDS issue on my 2011 Jeep Grand Cherokee Limited, Hemi Its amazing that after all these posts Chrysler has not done something about it.
