I bought a 99 Dodge Ram 1500 in Dec. Great truck. However the other day I got some gas and it ran fine. When I left work. It started running rough and the exhaust smelled like old gas. When I get into the gas it levels out fine but when I get back to cruising speed 60-65 it runs really rough. I am no mechanic can someone point me in the right direction. I have since ran the gas out of it and put some good gas in from a well known c store. I put fuel injector cleaner in it but it is still running rough.

This truck is my baby help me get her back to good health.

Thanks

check plugs.

 

Run It for a few more days, the old gas is probably not completely out of the fuel system

 

The old gas is still in the system. I think most fuel injection systems return fuel to the tank, which means bad gas keeps recirculating. Take it to a parts store and let an employee hear it run. They can usually tell whether you need injector cleaner or water remover. If that sounds crazy, I work at a parts house and folks come in all the time to do that.
