hi, i'm newbie at here and i need to ask the prob i got at my car, my car is wira 1.5 injection.
one month ago, i starting noticed got some prob happening to my engine , the rpm starting to rise to 2k rpm, then suddenly it run between 1.5k~2k rpm.
i go to eon service ask, the mechanic told me is "surbo ic" prob, need to change new 1, cost around rm1200 , but if buy outside(from spare parts shop) will cost around rm700+some labour charge for them.
this happening for quiet a time, then recently it become normal again ,then last week the prob caome again, this time is the engine rpm low , the rpm less than 500rpm, so when i stop, if i don't step on gas pedal, the engine will stop running
so the prob of my car engine now, is
1.rpm running at 1.5k~2k rpm frequently (just like got ppl step on gas pedal)
2. rpm under 500rpm
3 rpm normal (around 600rpm)

so, now everyday when i start my engine, i will face 1 of condition above
