Anyone has overhauled their Wira engine before?  My old Wira has started to consume engine oil.  Mechanic says to open up the engine, change the rings, etc.  Or even go for a full strip down of the engine.  Price he quoted ranged from RM1K to RM3K - 1K to just change the rings, RM3K for a full strip down. 

TIA.

yeah i did my overhaul a couple of months back, it really consume lesser petrol.

What was your rpm when you turn on the aircond?
Suspected faulty ISC, rpm too low when in gear hence vibration

RPM was in the middle of 0 - 1. my normal rpm without air-cond is slightly below 1.
btw what is isc? is it because of lack of power supply?

That is what I expected. The ISC gears are gone, you need to get a replacement

But before you do that, do clean your throttle body first, a dirty throttle body can cause idling issues as well

ISC gears means?? sorry for asking a noob question.

Its a very common problem with mmc totobodi, ISC (Idle Speed Control), it'll auto adjust to prevent the car from stalling or dying whenever the a/c kicks in or cold start if nt mistaken.... vry famous problem that most mmc owners cant avoid...

Does installing a volt stabiliser and grounding cable helps?
