Lancer GLXi ..idling problem

[BoEinG_747]

mga bossing help on this naman ...
bakit everytime start ang car ...ang taas ng idling ..

pero after 15 secs ay bumabalik na sa normal..

vacuum hose kaya ang problem ?

[mackvil]

maybe just the auto-choke feature... to warm up the engine.....

if it keeps on changing after normal use..... maybe the servo.....

btw, i am a former owner of lancer glxi

thanks sir mackvill ..pa tsek ko po mga sinabi ninyo ...marami salamat po

[BoEinG_747]

sir mackvill..pahabol ko na rin .

bakit ang luwag ng shift lever niya ..

at maingay pag mag change ka ng gear

ano kaya posible sira ? my mga rubber bushing ba ito ?

TIA

for EFI cars, high idling at start up should be normal, it should be at least around 1200 RPM at start-up, meaning engine has not reached it's ideal temperature and just like you said, after a few seconds idling should drop to normal level.

What you should be worried about is when the idling constantly fluctuates from high to low whenever your A/C is on and everytime the A/C compressor kicks in.

as for the shift lever, if you have the Itlog GLXi, there should be a plastic bushing at the bottom of your shift lever, baka worn out na, mura lang yan at madali lang palitan.

thnx sir Artpogi

try ko check after work ng mga advice ninyo

the best talaga mga peeps sa tsikot

Basta bumaba yung idling after a while ok lang yan, yung sa akin mga 3 minutes sya nag i-idle at around 1500rpm pag cold yung engine to warm it up.

thnx sir Chris on some inputs

chief, how do you adjust the idling speed for EFI cars? mine reads 1200rpm at start up then drops to 800-900 when the engine warms up, kaya lang when i turn the a/c on it spikes again to 1200rpm then gradually goes down to 1000rpm thou hindi naman ganun ka eratic ang fluctuation nya. does this mean i have a problem with my servo? kasi i'm used to carb type engines where i can adjust the idling and a/c actuator by simply twisting a couple of knobs. i was thinking of simply adjusting the distributor cap position kaya lang hihina naman with the a/c turned off. i wanna tone down the idling sana while the a/c is turned on for fuel consumption. any ideas? thanks.

by the way, i'm having that problem with my nissan presea (eccs).

Dude diba normal lang ang behavior nyan? AFAIK what you're describing (high rev on cold start, etc) happens on all servo-equipped cars. When your compressor kicks in the servo detects the added load and adjusts the engine's idling accordingly.

yeah, i think so. but is there a way i could adjust the idling speed while thea/c is on? kasi medyo natataasan ako sa 1000-1200rpm. i wanted sana 800-900 with the a/c and headlights turned on. kasi with my previous carb type engines, i get to manipulate th idling speed both with a/c on and off (mataas lang ng konti with added load)... is it possible with efi engines?

[JohnM]

I don't know if it's possible. Baka kasi hard-coded sa ECU ang rev and load values. Those who have Nissans should be able to help you. Sa Lancer ko kasi isang screw lang sa taas ng throttle body ang adjustment. When my mechanic adjusted my idling the aircon and all other accessories were off. You don't have to touch the throttle cable adjustment anymore.

[arj]

what do you mean by "i don't have to touch the throttle cable adjustment" yung "nut that adjusts the throttle cable? uhm... i don't usually touch that, what i can't seem to find is the throttle screw & a/c actuator screw (if there's any with efi' engines).

thanks btw.

[JohnM]

Dont have pics but you can't really see the screw per se. It's just a screw head sunk into a hole on top of the throttle body. HTH.
