Engine Mechanical problem
1992 Cadillac Fleetwood V8 Two Wheel Drive Automatic 161000 miles
My car smokes when I start it in the morning, until I run it for a while. When I drive it, it tends to stutter especially when i'm turninig and giving it gas. It's kinda running like the fuel isn't getting to the motor. The guy who sold the car to me told me to put regular in it so I did and it already ran like it was idled to high at stop signs. Can you tell me what's wrong? Now I have started to use premium fuel, but it's still running a little ruff. And when I take off it sputters and smokes.
