help!! idling problem!

[Mamar]

guys may problema ako sa oto ko kasi napapansin ko pag mainit na ung makina ko pag umaandar sya ng mga around 2000rpm or more tas pag bigla akong nag neutral o nag minor ung rpm ko bumabagsak ng sagad halos 0rpm na minsan tapos babalik na sya sa normal, lagi nalang ganun pag nag rev ako tapos minor bagsak na bagsak ung rpm ko bago bumalik sa normal idling na mga 700-800rpm, misan nga namamatay pa ung makina!

Anu kaya problema nito kasi kalilinis ko lang naman ng feul filter pati ng throttle last week nde parin nawala!
bad trip talaga sa trafik eh, mayat maya na mamatay ung engine!

on or off ang A/C?

nag-e-engage pa yung magnetic clutch ng compressor mo kahit off ang ang A/C?

[m_ron]

which car?When did you notice this symptom?Are you taking medication?lol,j/k.

[lowriderz77]

have your servo checked sir

pag naka on lang po ung a/c!

ung civic sir po!

ang nang yayari pa naman pag bumabagsak ung rpm sumasabay ung kuryente nung oto from mga 14-12 sa voltmeter!

[afrasay]

mar,
check your electricals. could be loose connection somewhere.

looks like an idle control valve problem

sounds expensive, wag naman sana!

will have it checked again maybe later!

sakit talaga to ng civic e. pacheck mo yung IACV. if ever kailangan magreplace, mga 5k+ yan sa banawe.

[speedyfix]

linis intake manifold, tb and sensors lang yan...

kalilinis lang po ng trothle body eh! try ko din palinis ung manifold

[baludoy]

pareho ata tayo ng problema bro. iyon nga lang wala akong voltmeter kaya di ko alam kung sumasabay ang bagsak ng kuryente. pinatingin ko sa mekaniko ko pero di ma-remedyohan. patay sindi tuloy ang compressor ko pag naka-on ang aircon. malinis naman daw ang intake manifold. di lang na-check yung throttle body at yung iacv. saan ba located iyong iacv? help!

btw ang kotse ay '96 civic vti

mukhang ito nga. kailangan na linisin pati yung intake manifold and throttle body. gusto ko gawing diy pero baka komplikado kaya natatakot ako

if your mechanic cannot tell you where the iacv is then change your mechanic.

*speedyfix, hahahaha!

*mamar, it looks like your IACV is stuck.
quick test: pag malamig yung makina, mataas ba yung idle? tapos as the temp rises bumababa siya to normal 700-800rpm level? if so, the IACV is still working (kind of).

the symptom na when you press the gas and then release, hindi bumababa agad yung idle, seems like dirty IACV not responding quickly enough anymore. also try to check your coolant level because air in the coolant system can affect the IACV's operation (jumping idle).

kayang linisin ng DIY yung IACV, pero don't expect massive improvements. i think when the car gets old idling problems become prevalent, this seems to be common to all brands and makes.

but if i were you, i'd try cleaning the IACV first. in my case it was fouled with so much carbon kaya hindi na siya nag-re-respond quickly.

hehehe

honga eh. makes me wish i live closer to your shop more and more

anyhow, i'm in the mood for an attempt in diy-ing this stuff. i understand pwede silicone spray tirada dito. any tips? spray lang ba sabay punas sa iacv at patuyo? ganun din sa intake manifold and throttle body?

[orly_andico]

you need to remove the IACV from the throttle body, disassemble it (don't lose the teeny tiny cap and screw inside) then either wash it with gasoline, or douse it with carb cleaner.

took me a whole afternoon, and i dropped the teeny tiny brass cap _into the throttle body_ (got a big scare there.. good thing i was able to extract it with a tweezers, i don't want to think what would happen if it fell into the intake manifold and got ingested by the engine.. instant broken engine).

[speedyfix]

baludoy, actually regardless of where you are, you should know when you know more than your mechanic. when that is the case then take your car somewhere else.

^ point taken bro

medyo excited na ako sa diy na 'to for the weekend
