@matt wee
i do own waja 4g18 1.6Auto like u mention.....well the engine sound is normal and this waja 4g18 engine sound is especially louder when you rev or accelerating the car....so dont worry, the engine is fine and get use to it or play the music louder.... brows.gif

for fuel consumption, RM90++, i can drive until 400-500km for city drive,jam and a bit of highway driving with 100km-160km above most of the time.....gear change 2.5k rpm but mostly i will rev till 6000rpm..... and 1 full tank can easily get u 550km>>> if u drive mostly on highways...

what driving conditions u experience?

so bro, just get the car service 1st before u remonitor the FC again....change engine oil,ATF fluid, change the air filter and spark plugs (NGK/DENSO) and if can do tuning on the car as i believe the car around that age needs some tuning.....then i guess the FC will be fine back

gud luck and enjoy the car u get frm ur mom......dont think so much....just appreciate what your mom gave you... laugh.gif

haha i do appreciated it bro..before this i was driving satria 1.3 carbie in kl,totally underpowered i can say..and FC is damn high,that's why my mum let me drive her car...

And for my driving condition 100% in city only...mean always drive from wangsa maju-genting klang-titiwangsa(sometimes)-kepong(sometimes)...gear change at 2.5k rpm and if driving in city i never drive above 3.5k rpm...the same at highway..i tried my best to keep at 110km/h at 3.++k rpm only..but then still feel that FC is quite high.

And before come back to kl,i just serviced my car at proton SC,changed new original spark plug,change ATF fluid,change timing-belt,and re-tuning using MUT...total cost me about rm8++..

Your total mileage on RM30 of petrol is lower than mine by 40km.

Mine can reach almost 170km and even that I consider it to be very bad fuel consumption.

Just try to change the air filter and do so minor tune up should be okay.I already changed a new air filter,spark plug,gear oil changed.

Other than that its all stock.And btw,the loud engine sound is normal.When u rev that crappy motor up to 3.5k,it will be very noisy

your sc guy , cannot tune the efi system. furthemore your car has a transmission control unit . He can only check your vehicle diagnostics.

your fc could be high due to many reasons.

1. did the sc gap the spark plugs correctly ?

2. your purge tank is working ? a 4G18 feature

3. how often your auto transmission fluid is changed ?

4. what is the mileage of the car ?

5. are the fuel injectors clogged ? did you change the fuel filter ? is the fuel pump still optimum

its best you check a whole lot more. give us a call if you need more help. tongue.gif

Do you any humming bass sound from underneath ur car?

I have a leaky exhaust but dont bother to fix it cause its not really bothering me that much.

Changing fuel filter helps abit.

Oh just saw that yours is an auto.Then I think its normal.Auto are much more bad in FC.

Mines an auto.

Yeap 700Km with 50 liter.. all you need is maintain you car speed all the way between 90km/h to 120km/h, never push your car higher than 3500rpm...

Are you serious? 180km/h is at 4.1k rpm? or 5.1k rpm?

May I know what is SC?

Anyway I'm a new driver, I'm quite confuse on accessory shop and those big shop who does repair on cars.

For tuning those, do we go accessory or what?

Last time when my cigarette port got problem, i went to those shop that got a lot mechanic, and they tell me to go accessory shop.. =.=..

I'm driving a Waja 2003, just got it from my dad recently.

The first time I pump full tank, can go 450km, the second time i pump (currently the meter at half tank), already 270km, I don't think i can hit 450 this time.

I was thinking whether I should get something like this ..

http://forum.lowyat.net/topic/317872

Or Voltage Stablizer to lower my FC.

U will get higher FC if u refill amount RM20-50. If u wan to save money for fuel, u need to refill full tank as u can get lower FC.

WHY?

Cos if u refill half tank, the fuel or we call it as GAS will disappeared to thin air as the empty space of your half tank allow the fuel touches the side or top of your fuel tank when your car is moving. I think most of Wajarians who have low FC all make their tank full every time.

So my advise, make it full tank every time when refill. Its can save Cost, Fuel & Time.

agree with you. considering that the cps in waja kick in at 3.8k rpm, at 180km/h, the odo could be anywhere near the redline.
my stock 4g18p already showing 4.5k at 155km/h....
front using 195/55/r15 and 205/55/r15 rear. slightly above manufacturer's recommended pressure.
from my experience, fc wise, waja auto could easily cover well over 550km. seldom rev beyond 5k, btw.

Is Waja better with NGK or Denso? I heard rumors said Denso Iridium is better.

Sigh, I'm suffering for the fuel I'm paying for my Waja, pay RM 50 can only go fro 250km.

So the thing I'm going to change is :

- High Performance Plug Cable
- Denso Iridium spark plug

Must I go to the Service Center to change my engine oil? Or I can do it myself?

Actually my next service meter is not reach yet, so I don't know why it's high fuel consumption.

Bring to mechanic, ask them take out the trottle body and wash it with good carosin. Then use a bottle of fuel injector system cleaner. Bring to workshop with restorer machine to clean off the valve... you will feel your car lighter..i just did the above two to my 10 years waja auto...smooth smotth.. lalala

check your exhaust system maybe has leaking and change your extractor to aftermarket one might reduce the fc.
