high idle RPM at engine start

[Rjmar]

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,

Normal po Yan saken inde bababa need pa re start everybody can share same as my experience so I have an idea what part need to be replaced
