CAR SPUTTERING

1994 Chevrolet Caprice • V8 2WD Automatic • 114,000 miles

My car starts right up idles fine for a minute or so. Then its starts to sputter a little. When I take off, it sputters and car shakes until I give it more gas. If I let up on the gas pedal it seems to catch a gear and run normal. Worse when going up hill! 1994 chevy caprice

Foul/defective spark plugs.
Open spark plug wires.

Note: If it doesn't apply disregard it
