Mds

[Coyote with a roadrunner]

I am wondering what the concerns with MDS are? I have read several comments on here that are negative, but do not have any explanation. I have a 2006 Ram with MDS. It has 45,000 miles on it. I bought it new and have had no problems. I guess I am just curious.

Dunno. It kills fuel, spark, and leaves valves closed on cylinders it's not using. Guess (like anything else) something could go wrong.

btw, you have to maintain a steady speed for 2 minutes before it will become active
