Hey Scotty, I have a 93 Buick Regal with 200k miles. The engine likes to jerk or stutter when I start it, but later on stops. I replaced wires, filters, and spark plugs and no fix. What could this be?

You can check OBD1 diagnostics for any stored codes.

I'd say if it has its original 30-year-old fuel pump and fuel injectors they're suspect.
