'89 Wrangler 4.0 has developed a periodic miss while at idle rpm's while
sitting at a stop....say waiting for the light to change. Vehicle has an
auto tranny.

Hi Jack,
Miss firing is almost always spark plugs and with your age,
ignition wires, and probably an air filter with over twenty thousand
miles on it. Treat it to a tune-up.
