I have a 93 Chevy lumina (Eruo) with a 3.1L and it is runnig rough. It sputters it chugs when you step on the gas and the exhaust has a rattle to it. Now i fill this car up one day at a cheap Ma an Pa type station then the car ran hot and started to run rough now its really bad i changed the thermostat and it doesnt run hot anymore but still has all the other problems. Do you have any Idea
