Idling and aircon

**ineedmorehp** · May 6th, 2006 12:12 PM

Normal ba yung idling na 'to? Yung pinakamababa naka on aircon, un isa naka off.

**enricosantos** · May 6th, 2006 10:58 PM

parang medyo mababa yung idling mo pag nka aircon

**bluechip** · May 7th, 2006 12:47 AM

i guess its ok. kasi pag on aircon parang additional load nakasi yan kaya siguro bababa rpm mo...

Ayun. sawakas me reply. Hehe.

Btw, isa din pala sa prob ko aircon, aside from idling. Nde naman amoy freon un cabin; paminsan pag mainit patay aircon. Kung may tagas diba the next day d na sya lalamig at d na "pipitik" un compressor ng aircon? tama ba? Nabasa ko din un isang thread re Otep na compressor maaring prob, d na co compress? Kung compressor, mahina or may singaw? Kung may singaw d narin "pitik" un diba?

On idling
Fresh start 1K+
10 mins - as shown in attachement un 5K (aircon off)
10 mins - as shown in attachement un less than 5K (i guess and aircon on)
Parang may mali eh.

pa check mo nlang bro.. libre nman ata yan pa check up eh.. pa check mo actuator and idle something.

i assume carb type pa yang car mo

bro baka sira lang actuator mo or yung idle diaphragm butas na. ganyan din kasi sakit ng ride ko ngayon kaya lang hindi pa ko nakakahanap ng diaphragm. Or baka maluwag lang hoses mo papuntang actuator. For now ang ginawa ko munang remedyo ay dinis-connect ko muna yung power ng actuator para konti lang difference ng rpm pag on yung aircon tapos tinaasan ko yung idle sa carb para hindi masyado mag vibrate yung engine

ineedmorehelp,

your pics show ~600rpm and ~700rpm ... the first mark (thin line) above the zero mark (thick line) is 500rpm ... the tachometer do not have enough sensitivity to indicate rpms less than 500, hence it is marked that way

now that you say rpm is lower when a/c is on (600rpm), when it should be higher than 700 rpm (idling a/c off), then only a minor adjustment is necessary, say 750-800rpm with a/c on ... assuming the car do not have defective parts related to idle-up mechanism

i have observed most cars would idle without much engine vibration at 800rpm with a/c on ... but it is best to check you car's specs for this so that you would not unnecessarily waste fuel at idling with a/c on ... or just make your adjustment for the lowest rpm where engine vibration is minimal

yes, when much of the freon leaks out, the compressor will not work because the pressure switch will remain open, depriving power to the clutch solenoid of the compressor

good luck!

Medyo may 'vibes' sya pag naka A/C. Btw, the idle should go up when the A/C is turned on right? Not in my case

I believe the reason for that is to compensate for the power being reduced by the A/C compressor right?

Good thing atleast medyo safe ako walang tagas para mawala freon.

Oh btw, i heard a cracking sound whenever i step on the gas at the same time aircon turned on. Anu 'to compressor na talga?! OH NOH!

**bonch2484** · May 8th, 2006 06:34 PM

ako din, ganito rin dati idling nung car ko... i had it adjusted sa shop kaya lang sumobra naman ata... papatingnan ko ulit, aksaya sa gas eh... Tapos ngayon, ang lakas ng amoy nung gas... possible kaya na may leak yung gas tank ko? Pero wala naman ako makitang tulo sa ground...
