my problem is when the aircon is on, the engine idle is rough. sometimes the car stalls during neutral. when the auxilliary fan automatically turns on, ok naman nasa 1000 rpm yung tach reading. pero pag nag auto off, bumababa yung idling ng .400 rpm minsan lower kaya nagstall minsan pag naka neutral. pero pag nag auto on yung auxilliary fan, balik 1000 rpm ulit yung idling. pag naka-on lang naman yung aircon nagiging rough yung idling. ano kaya yung problema peeps? pls help. ride ko pala '97 exsior. ty.

December 2nd, 2002 11:18 PM #2Same problem with mine, pero intermittent siya.
Baka wiring problem sa a/c, may grounded somewhere, or yung idle-speed controller (or its nearest counterpart sa mga Toyota) mo may diperensya na.

December 10th, 2002 02:35 PM #4try to check yung karga ng battery...go to a reliable battery shop
or an auto electric guy to check the output voltage of the battery
kainlangan yata is 14volts pa rin ang reading nito kahit
bukas lahat ng lights and accessories mo..even yung aux fan...
and malalaman mo rin dito kung sira ang alternator mo..
ang nangyayri naman sa akin..pag sipa nung dalawang aux
fan parang lumalabo ng konti headlight ko..pero bumabalik din
naman...and hindi naman rough ang idle....

September 14th, 2005 12:51 AM #7hijack at buhayin ko lang muna itong thread...
problem ko rin ito, rough idling pag naka on yung aircon. while driving ok naman. pag off yung aircon ok na rin. malinis naman yung IACV. tapos pansin ko yung idling di nagbago nung on yung aircon.
meron rin bang idle up screw or whatever you call it sa PGM-FI (fuel injected) na engine?
ok naman cguro yung battery nito dahil wala pang 6 mos., yung spark plugs naman around 5k km pa lang. na-reset na rin pala yung ECU dati.
vehicle is a 95 honda accord

pag nag-off yung aircon merun whining sound sa engine bay. after mga 5 seconds mawawala yung noise, then bababa naman sa 500 yung rpm. when i step on the pedal balik sya sa 800 rpm. vacuum problem kaya to? idle-up switch?
btw, brand new battery ko.
