Hi sifu's!

Need some advice. I got my carburetor tuned by the mechanics at Proton. They managed to set my RPM for both Idle with air/con and Idle without a/con to around 900RPM (definitely less than 1000RPM). However the next morning when I started my engine I found the RPM to be very low (around 500RPM). Engine was shaking bad and almost like want to die. Before this whenever I cold start in the morning, the RPM would go to 1000RPM and stay there until engine warmed up.

What could be the problem? Can I do it myself or should I bring it back to the mechanic?

Really appreciate advice. Thank you in advance.

How can I confirm that its the autochoke that is spoil? Went to another mechanic today and he increased my idle RPM to about 1200RPM. He said to try to start tomorrow morning (cold start) and see if the RPM is still at 500RPM.

BTW, which is the autochoke for the car? If the vacuum hose is 'sumbat' can it cause this problem?

Hrmm...I'll bring it over to Proton SC tomorrow to ask them to check it out. Problem is if it is really the auto-choke that is condemn the SC doesn't keep stock (need to order from KK). Hopefully the spare part shop here got the item laa

Sent it to Proton SC. The mechanic did something on my carburetor and now the cold idling problem is gone. Started my car this morning and it idled to about 1000RPM during cold start

Anyway, was wondering if any of the sifu's here have changed the absorbers for LMST Iswara? What type is recommended? The stock ones are a little soft especially on the bumpy roads here in Labuan
Should I use softer shocks or stiffer ones? Or should I look into changing the springs instead?
I don't want to lower my car (want to maintain the current ride height )

Any suggestions on what type of absorbers I should use to replace my stock LMST shocks?

Was thinking of replacing the whole set as my car seems to be 'bouncing' up and down too much on the road now a days

Can the APM Absorbers be used with the stock Iswara springs? Or is there a matching spring that I can use but still retain the original ride height?

BTW, is the Kayaba Gas stiffer than the original absorbers but softer than APM? Can they be used with the ori springs as well?

I see. But there is no problem to pair the Kayaba Gas absorbers with the stock springs right? Or do I need to change the springs as well?

Thanks for the advice. Will look around town for the Kayaba Gas Shocks. Hopefully can get it installed by this year
BTW, how much does a pair of the absorbers cost? Want to make sure the shop won't 'potong' me with the price

Another thing forgot to ask, if I plan to change the springs in the future but want to maintain the standard height of the car, what spring is recommended? Looking for a balance between handling and comfort.
