1991 Chevy cavalier 4 cylinder.
My Mom's 1991 Chevy Cavalier 4 cylinder has
started sputtering and she's wondering what
causes it to do so and what kind of repairs are
needed if any.
There are a few possibilities that causes sputtering. Start with the plugs and plug wires and if they're good, check your fuel pressure. If there's a check engine light, have an OBD hooked up to check the engine codes and that'll pinpoint the exact problem.
A good fuel system cleaner in the gas would also be a good idea.
