I have a 2000 Ranger 2.6L 5 spd that idles too low, it used to idle fine then started getting lower. Occasionally it's normal but more often it's low. Cold start it's low enough to stall, warm is not much better. Someone said I might clean the Mass air flow sensor( I think that's what he said). If that's true can some one guide me through the process? I'm not up on all the comp. stuff on trucks.
TIA, Al
