high idle RPM at engine start

**butchokuy** · December 2nd, 2007 11:24 AM

hi mga gurus,

tanun ko lng.. nu kya problem ng car ko - lancer glxi 93

pag start ako, ang taas ng idle nya mga nsa 3K RPM, stay sya dun ng ilang sec then bumababa dahan-dahan hanggang s 1K.

after nun, normal na kahit s trapik or nka-stop.

bagong palit lng ng servo neto.

many thanks in advance,

idle up po yun,

pag umaga/unang start talagang ganun on most cars kasi wala pa sa operating temp ang makina....

ganyan din kia pride at maxima ko...and take note, carb po mga to...

normal lang yan bro sa mga EFI, lalo na bago pa servo mo. Technically called as FIS (Fast-Idle Speed), counterpart ng 'auto-choke' naman sa mga carbs.

normal lang yun saken before nasa 2k rpm eh, tapos kapag aalis ka na sa umaga
pag gear mo sa 1st kakadyot pa hehehe taas kasi eh hehehe

pede ninyo i-adjust yun cold idle sa carb engine. medyo mataas ata ang 2k pag malamig. sa mga auto na normal idling na 700-800 rpm mga 1k to 1.2k pag cold.

Ang taas naman ata na it reaches 2k-3k rpm, siguro mga 1.5k rpm okay na though sa diesel since low rpm lang di pa ata umaabot ng 1k during starts eh. Pa adjust mo na lang konti para di masyado matakaw sa gas at ma lessen din ang stress ng engine…. Lalo na cold starting is very important in engine life.
