Rpm

[pitbrad]

sir, normal lng ba kung ung rpm ay bumababa pag naka AC? from 1000 rpm to 600 rpm, corolla 95 MT, 12 valve, carb.

hindi sya normal, should be the opposite dapat tataas sya to compensate sa load ng aircon. first of all masyado mataas ung idle mo without aircon. it should be below 1000.With aircon, it should be around 800 to 1000, without aircon it should be around 7 or 8 or anywhere above 500 and below 1000. Basta and concept is pag nag aircon ka dapat tataas sya and hindi sya dapat bumaba.

its either you would need to adjust aircon idle screw mo (or whatever it is called) or hindi na gumagana ung idle up mo. pero if i where you i would play around with the ilde screw first. un ung screw na may spring usually found on the right side of the carb {pag nasa harap ka ng kotse}. Ung nasa left na screw na may spring choke un.

aircon idle screw (or whatever it is called) - clockwise para tumaas ung idle. counter clockwise will do the opposite.
