Newb here... Long time reader first time poster. Marami na ako nabasa dito about the idling problem of Mazda 323 familia when the A/C is on and done the suggested solutions pero ganun p rin.
Here's what i done:
1. Pinalinis ko na yung Throttle body sa servitech near us (fairview).
2. change air filter
3. clean the MAF sensor with a contact cleaner
Like other stories, my problem yung idle ko pag naka-on yung aircon bumababa it will drop as low as 300rpm pero pag-off mo naman ok siya. Baka mayron pa ako di nagagawa na pweding solusyon sa probelma ko.
pards, try having the aircon actuator checked baka may crack..
if ok naman, try having the distributor adjusted. i think may marking dun na 3.5, medyo ilapit mo yung marker don para tumaas and macontrol yung idling... lalakas din hatak nyan.
