Guys,

as i mention earlier after replacing the idling vacuum it was fine for 2-3days...
i've continue monitoring it.. but came back to its existing problemo....
its still revving up to 1200rpm or more... but the funny part is it goes up
either when i hit the clutch to change the gear or else when i switch on the aircond...
sometimes it stays at 1000rpm... but most of the time its more.... relly funny... However, i got an advice from my fren...
he mentioned it could be due to VVT pulley as well. yea my engine has that
"diesel" noise yet does it effect the timing as well?? anyone could advice me on this please?

expension tank level when cool time will at min-line then top up to max -line level for a
week!... izit normal for the 4age engine ? seem like the 4age hotter compare to other car
!? or my car got some problem d ?
2)after 2000 mileage engine oil will reduce abit when ramp n drive fast ! but if normal
condition driving for 5000mileage, engine oil not reduce !?... what is this issue ?!
engine oil = wyne 10 40W + blue chem oil system care

any sifu can share some knowledge !?

try to check ur steering rack vacuum hose, if tertanggal or poor hose condition will cause the problem u mentioned..
if everything tried, it's time to change blacktop wiring running MAP...hehehehe!!!

 

[Cronixz]

I realize my steering rack oil seal is kind of leaking .. but very small leakage... could it be due do that???
