I was driving my ranger at 50 mph,on level road when I heard a slight snap or pop and the truck lost power. The engine remained running but the truck would not go above 25-30 mph. My usual shop has had the truck for a week and can't find the problem. There is no DTC displayed when scanned and no check engine light. I suspect a clogged cat, muffler or collapsed pipe, but the shop manager does not want to believe this could be. Anyone else experienced this problem? Thanks for any help.
