ENGINE IDLE SURGE

1993 Ford F-150 • 200,000 miles

Engine surges at idle and at low speeds like {5 to 10 miles per hour} I have changed fuel filter, spark plugs, wires, rotor cap & button, tried various name brand fuel & injector treatments, All to no avail. Please help me find the solution to this problem, because I love this old truck. Thank you in advance for you assistance Sincerely : John

Try cleaning the throttle plate on both sides with choke cleaner and iac hole first. Then check fuel pressure
