Abnormal idling: 2002 Altis 1.8G

**Ungas** · November 2nd, 2003 11:09 PM

It's my turn to ask... :D

Di po normal ang idling ng Altis ni erpats, ang naalala ko dapat nasa 1k rpm and when aircon is on it should rise up a bit more. Pero ngayon bumababa ng below 1k to a point that the engine stalls in the middle of the road. Eto pang siste, MATIC!!! Engine won't start unless you put the tranny back in P position and step on the brake.

Kung normal stops at an intersection, ganun din. Pag bagong andar ang makina it revs upto 2k when the engine is still cold. Ano kaya ang problema nito?

What was I thinking of?!? Mods paki-edit na lang yung title, it should read 1.6G.

ganyan din naging problem ng E36 ko dati. i narrowed down the problem to dirty EFI. i had the fuel injection cleaned together with the fuel line and the fuel tank. changed the fuel filter and had the car tuned again.

since bago pa yung corolla ng erpats mo, you may reasonably rule out ecu and solenoid problems for now.

I was suspecting the same culprit. Btw, Toyota did change the faulty fuel filter 8 months ago.

1k po ba ang normal when the aircon is turned off...?

Yung sa sedan kasi namin (1.6 din), ~1.2k kapag bagong start tapos .8k naman kapag nakuha na niya yung tamang temperature. Kapag binuksan mo yung aircon, doon lang siya tataas ng 1k. :D

mataas yung 1k for a normal warmed up idle. 800k lang dapat.. and when AC is turned on.. idle up brings the idle back to 800 instead of dropping the idle.....

krscla,

yang idling mo ay ang ideal idling.

at cold start for EFI engine = 1200 - 1400

once engine reached ideal temp w/o AC = 800

once engine reached ideal temp w/AC = between 900 - 1100

Pino kasi ang lines below 1k ng Altis kaya di ko gaano napansin. Less than 1k, malakas ang engine vibrations. Above 1k pino ang takbo ng makina. Tsaka alam ko mas mataas ng konti ng idle ng makina pag matic versus manual trannys.

Edit:

Hindi pala umaabot ng 1k kapag binuksan yung aircon, hanggang .9k lang tapos after a while, balik ulit sa .8k. Matic din yung car.

Medyo mataas nga ang 1k kasi yung isa naming sedan na may problema sa idling, .9k ang "normal". :D
