Ignition upgrade , What do the plugs look like ? It's 20 + years old try a simple compression test . Have you noticed an earlier drop in gas milage and performance ?
Most likely the service engine soon light is on. Visit your local auto parts store and have them scan the computer for trouble codes. Post the codes and we can help further. Jim
Awesome! Thanks for letting us know! Replace all three. If one has failed the other two are soon to follow! Glad you fixed it!! Jim
