Very hard to say geh, few things concern lar

1) Sparkplug really die jor
If sparkplug die, the car power will affect severely right?

2) Throttle body dirty jor
I suspect this one too.

3) Air filter dirty jor
I just serviced 1.5k ago, cleaned using air gun, BTW, K&N drop-in here.

4) Petrol dirty? Injector sumbat?
Petrol dirty not sure, my fuel filter just changed 1.5k ago. Injector sumbat i suspect too.

5) Vacuum hose leakage/disconnected(but your car will die everytime you let go gas pedal and hit the clutch)
Never happen before and after the incident.

6) You too light footed until engine die jor also havent hit the clutch?
Impossible. When i saw the car is in front, my speed is around 60km/h+ @ 4 gear, i just press clutch and shift to 3rd gear to standby and release once i exit corner. The left hand corner is slightly uphill once entering corner. I loss my power steering after 2s i clutching and before i release clutch.

7) Catcon sumbat jor?
This one not sure.

8) This 1 you don't want to know, hutan bakar incident, CO sensor too dirty jor. But then your car will be hutan bakar and very hard to drive, the car will keep on farting like a misfiring system rally car.
No such symptom observed.

It'll be helpful at this time if you can observe the vacuum gauge

Not necessarily affect FC geh

1) Old plug can still function as good as new, but if 1 of them die the car will also easily choked off and dieded. Prior to all this, very noticeable is hard to fire up in the morning, cold + long stationary.

2) Our throttlebody is already OVERSIZED in a S4PE. With that kinda diameter, can fit it in a 1JZ. Dirty will not cause much different in FC, but tend to leak vacuum may cause die engine when low speed cruising

3) KNN also need to wash. I've heard KNN's oiled up filter, the filter oil may cause dirty to map sensor, as a result dust will be collecting on such sensor... Not sure how true is it, but I'm using WD40 to oil up all my any other racing filters/drop in hai flow filters

4) Petrol dirty or not, you me also dunno geh. Need to observe few more tanks

5) If not vacuum leak, then no much to worry jor. May be this is the only time

6) I was just assuming. Sometimes I accidently die my engine at traffic light pickup

7) If catcon sumbat, engine check will sometimes lite up. Can get exhaust guy to check

8) Hutan bakar itself is a bad chain reaction, as any of the above and cause 1 to trigger another, and ultimately hutan bakaring.

I think you should just sit back and relax. There is nothing much you can check/do/repair for now. Give it another few more tanks to observe how it goes.

bro, that api ribut really efficient, really enjoying my ride than ever before... 
let's meet up for UOTT after your exam... 

yes.. ada wee wee sound abit.. but its filter it mar..

my car now smells good..

sometimes when you drive alone at night.. when you alone... ~~ the sound so spooky..

Sky Net coming for you. Judgement Day arriving soon.

i must say my blm sound insulation really tak boleh tahan 

highway cruising at 90 and above, normally radio sound will be covered by engine + road sound 

my GaGa inspection date 2/2/2010, how cum use SIEMEN ECU geh Luke, when your GaGa SE born wor? How cum different geh

Or izit bcoz Conti ECU save more petrol

now its very obvious, 2 of our FC king in LYN GaGa porum got Conti ECU regardless how I drive my GaGa with proper vacuum efficiency, it just wouldn't work as good as Luke's Conti ECUed BLM SE

Now, where can I get a Conti ECU
