Mds issue?
I recently swapped a motor out of my 2009 ram 1500 5.7 4wd with a 2013 5.7 and have had issues with the truck kicking the check engine light on for a cylinder 3 miss fire when I’m accelerating over 3.5 rpm on occasion. It also occasionally has a rumble at cruising speeds around 55mph which I believe is the truck trying to put itself in fuel saver mode but doesn’t. I have 31 off road wheels and tires on the truck and from threads I’ve read said that the truck will do that because of the alteration in wheel size. This morning I jumped in the truck and drove to work with no issues. Stopped and filled up with fuel and pulled out and it acted like I was only running on 4 cylinders with little power so I pulled over. Shut the truck off and started back up (engine is hard to crank when warm) and seemed to run on all 8 again with no issue. Anyone have any ideas?
