Need Help Urgently..........

[ryuichi]

Bro,
Something wrong with my 20v SVT manual. Let me share a few scenario:

1. Previously, my fuel consumption(FC) for city driving is at 38L = 460km while highway driving is at 38L = 590km. Now my FC climb up very steeply to 38L = 300km only which translate to about 20cent per km, equivalent to auto cars.
So, anyone have any idea what is wrong?:frown:

2. When i start my engine in the morning or after the engine had cool down for more than 3 hours, at first idling is at normal(900rpm), after a few sec it drop till bout 500rpm n less, like the engine want to mati but it won't mati.
While driving it's ok but when it stop at traffic light or during jam, idling drop to 500 rpm for a few sec n climb back to normal.

3. Another thing is my temperature indicator on the meter panel. I notice whether it's during daytime or night time, whenever i rev above 4500rpm, the temperature indicator starting droping. The more i rev the more it drop. When rpm is less than 4500 rpm, the indicator went back to normal.

So, any sifus have any idea what's wrong with my svt or anyone experience it b4? Something is really wrong with it.....Anyone can help me on this......?

Bro, 38L=460km town use ar? si beh save fuel man.... mine is 38L= 380km lah dude.

as for ur second question. i m experiencing the same prob lah. so i guess it has something to do with the throttlebody or the o2 sensor.

the water temp mine is normal. i think u need to check check the fan or the radiator lah....

Swap,
I understand what u r saying but it never happen b4, it's only recently that the temp indicator a bit crazy ......it goes down d**n fast man.....it even reach the lowest point le....

dreamy,
I'd my air filter wash n cleaned and oso the plugs changed already, but still the same......

george,
yup, it's correct man. My FC previously was very good, 38L=460km for town use.....it last for 1 1/2 years till now.....

2slow,
i'm not sure but i do doubt bout the throttle body.....

TRD16V,
i'd contact EFN oledi n make an appointment with him tonight but too bad he can't do the cleaning cause he got an urgent call back to office....so have to wait......

Bro,
For 20v svt, where's the location of the O2 sensors n how many O2 sensors for 20v svt?
And oso does anyone know where's the location of the temperature sensors as well?
LAstly, for 20v svt, which sensors triggers the ecu in running open loops?
Anyone can help me on that .....?

 

[ryuichi]

Thanks for all the replies.....
Problem solved by sifu EFN....!!!!!
Apparently idling valve n throttle no 4 was blocked which caused all the problem.....
Now happy revving with it......
Will check the FC in a few days time when it's bout time to refuel......
