Just hope that my idling stable for at least a year, otherwise I might go phuck the mechanic up.    He is not my regular mech, I only go there to do tuning. My mom's friend. Obviously my regular mech is much better but tarak tuning gadget.

I'm afraid the throttle body might still be dirty... 

How often you guys do spray cleaning? Will it be ok to do both, removing the TB and clean it and then spray cleaning again inside?

Can feel the ummphh, the engine is much more responsive than before, rpm naik faster.

How much it cost to do injectors cleaning? Does this included when I go for full overhaul?

Yea, tak mau Mivec anymore, give up, not as excited as last time. Now just want to keep the current engine healthy, able to last me for another 10 years or 300,000km. 

Fuel filter never change before, and so is the water pump. Timing belt change also coming soon, another 10,000km.

I might consider doing everything at one shot. Roughly about how muchie?

Engine mileage is 120,xxx.
