My 89 F-350 7.3 is idleing high. Ive adjusted the screw till throttle wouldn't go back anymore. The fast idle solenoid is also not touching so that too is not the problem. Truck idles smooth, There is small leak on top of fuel filter around heater plug. What should I do to lower my idle? The truck does not smoke. Even if you accelerate hard. So I don't think it needs adjusted but unsure. Any help would be appreciated.
