hello fellower ramers, i am experiencing a problem with my 07 megaram 6.7 ctd. ive noticed that lately when i start the truck it sounds muffled, like the exhaust brake is on and then when i put it in gear it starts stalling like it aint getting air or fuel. then i started looking around and just for the heck of it pushed the reset on the air filter gauge and started it back up and it was ok. its been doing this for a couple days and dodge dealer says its never heard of such a thing. just wanted to know if anyone has had this problem before i take it in. appreciate the info. wolf
