rpm...

if the throttle body servo kits still cannot solve your problem, then it
might be time to change the whole throttle body

[jigc]

i would suggest u to adjust the idle control screw, back down 250rpm.

Agree with zendengoh, it's time to change the throttle body already. No
point change the small small parts which last for a few month.

Thank you very much, and really appreaciated yr guides...

by the way, after installing the servor kits, do i need to tune or adjust
anything , because i only install back the gears n screws...

So , how much do i need to squeeze from my pocket to replace the whole
unit of the throttle unit?

u guys recommmend 2nd recon or new.?

Best regards ..!

i changed mine 3 years back when my Wira 1.6 reached its 5th year. That
time i spent RM1050 (inclusive labour, non-proton SC, should be cheaper
now). advice is not to take 2nd hand unit, unless u plan to change your
car in the near future. The TB has its own lifetime as well and it will
break when time reaches (~6 years). If the 2nd hand unit has run for 4
years, that also means that you have another 2 years to use. If you do
not have the proper tools, would advise u have it tune at the workshop.
Proton SC will use the computer device to tune (more accurate readings,
rpm and some other sensor readings) whereas those normal workshop will
use a "light-gun" to archive the preset rpm.

[jigc]

there is not necessary to use light gun for rpm adjustment.
it is for ignition timing adjustment.

but for wira, u need to ground the ignition terminal at firewall to adjust
both rpm and ignition timing, see link below.

pls clean up the TB first (deposit under the throttle) b4 adjust the idling
adjustment screw (at top of TB, near TPS).

your is 4G92 SOHC izzit ?

i am not sure what is my engine model,

but it is a 1994 proton wira 1.6 XLi (A)

i believe it is the 1st batch , still many parts from Japan.

regarding the advise to clean up the TB box, can anyone give me direction
or photo?

i m sure i changed the gears n clean up the dirt in the area....

Hi, I have the same problem with my 2000 wira GLI (M), any sifu can assist
me to getting a OEM (APM) parts. The proton parts are very expencise
yeah... Please advise what price will be reasonable ....
I wouder clean up the TB will help or not ? But in the forum of WIRACLUB,
DIY, do have some photo on it.... no time for thatlah....
