high idle RPM at engine start

[tph]

yung getz ko po ganun din...

may sensor kasi sakin sa panel kapag malamig ang makina...pag may ganun nagiging mga 1500 rpm yung akin hanggang magsettle sa 800-900 idling nya.

sa gli bigbody nasa mga 1.5k lang. For how long should the Fast Idle Start ba lasts or does is it based on your engine temperature?

[speedyfix]

a couple of seconds lang dapat mataas. at most 30 seconds.

[papavi]

similar problem din po sakin pero ang pagkakaiba, ung idling ko e permanent na nasa around 1.3krpm. ok lang po ba un? dati po kasi 1krpm lang.

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,

Puwede i try,
1. Palit air filter
2. Linis throttle body
3. Linis MAF sensor
4. Check spark plugs or ignition coils

there's this youtube article, about a 2000s altis, that had a high rpm on cold start (2000+ daw), that only gradually went down to sub-1000...
sabi niya, may leak na raw ang intake manifold.
fixing it is the solution, daw.

our 2003 altis, had a high cold start rpm of only 1500...
