should be fully paid right? just let it go, old car could easily turn into money pit. all those repair could do downpayment

No, I mean maybe your fuel filter is clogged, have you changed them before?

i think ur mechanic started out doing the right thing. sounds like u have ignition issues. if it were me, my first guess would be the spark plugs too. but rm100 is a bit much (my iswara plugs just cost RM30 a set).
clutch, driveshaft and timing sensor? thats pretty unlikely in my opinion.
my second guess would have been that u havent been servicing ur car regularly and your piston rings are damaged so they let in engine oil into the combustion chamber. this slowly builds up sediment on your spark plugs which causes a failure to ignite.
if it is true, then you'll need to do a top overhaul to replace the piston rings.

Check oxygen sensor. The symptom is car suddenly stall and can be restart after a while.

change to mercedes liao

Alternator

I don`t agree on this,

1. Even if you lose one, the car won`t just die, especially when you`re driving. the engine will just feel rough due to 1 piston not igniting.

2. If the piston ring is damaged, you would see black smokes by now. do see any? black smoke is due to engine oil is burnt together with fuel due to engine oil sip through the piston ring.

Yes confirm is the high tension wire.
Go change the high tension wire. Becos the 1.0 ej-ve confirm is using high tension wire and not coil on plug.

I bangla car mechanic can confirm this is true.

9 years+ you should consider changing the car. You know most car are beyond their economical usage past 7 years.

if you haven't been changing engine oil and gear oil on time every service period (typically 3 months or certain mileage whichever comes first) all these while, you probably need to do an overhaul. If you've been diligently doing that, then like some of the forumers said, start with simple stuffs first. Spark plugs, fuel pump, altenator, etc..

I've been driving mine for 13+ years and I don't really need to do any overhaul because I change engine oil on time every service period.

i bet on fuel pump and fuel filter

Send to Perodua instead of the money sucking ahbeng mechanic

i think not, first time hearing this though.. will take note..
how much would that cost me? 
oxygen sensor? If that is damaged, how much would it cost to change it?

Around RM 200.

I think you need to change your mechanic ler. Coz my car 10 years but 1.3 also dun have this problem as you stated. You should need the mechanic plug in a engine checker, not big device to the engine, then they will show you ur engine what error, this is where i know where my O2 sensor kong

i bet on fuel pump and fuel filter
