Hi, at 5th gear, 3000 RPM ,the speedo meter is pointing at 116 or 117 KM/h is it correct? it's a Waja 1.6 4G18 manual

Hi guys, I just got my car (mitsu 2004), and very happy with the car, except for the power window. I try and troubleshoot myself, reverse engineered the power window module, I manage to figure out the pin-connection, and seems to be in good condition, but when I plug-in, it fail to function. I'm going to investigate this down to the bottom and reveal the bad engineering of proton.

Anyway, that problem aside, there is another thing troubling me, the power steering. Whenever I turned the steering fast, i.e. during parking, I can hear "fluuuhhhss" kind of sound, I think it's the power steering hydraulic flowing through some restricter. FYI, the power steering work just fine. Should I be concerned about? Is that normal, or sign of breakdown?

Yup, mine around there, almost 120km/h. Just tested it this morning. At 130 and it will come to nearly 3.3k rpm.

Try change ur power windows to metal panel type...will solve ur problem.
Ya, its normal for the steering sound..especially whn u turn to the max thn the sound will appear.

mom's waja power window co-driver side is dying, signalling to change to metal type later.

but the metal ones are noisy

What do you mean by metal type? You mean the switch is metal? How much would it cost? This one is the driver side power window, i think is quite expensive. I got mine from the previous owner when I bought it. It's plastic. I think the problem is with the circuit board, couldn't be the contact.

Yup, the sound from power steering is quite obvious, with fast half-turn, can hear the sound already.

guys, can recommend me ATF fluid other than the proton

will do alot major services soon

I suspect it could be your window switch, mine also failed me few months back, cost me RM90+

the switch should look like this

Last nite just back from Kuantan, sprint my Waja all the way, then overtake a Perdana. Then that Perdana accelerate and back at my rear car. Still sprint my car and go to left lane until reach 190km/h. That perdana still can't overtake even i on left lane..hehehe..

halo..can i know what the FC for waja 4g18 AT?

pump rm50 roughly can go how many KM?

If not mistaken around 250km..hope others could answer. As my manual tranny doing 310km for RM50 nowdays.

wow rm50 for 310km is quite good already bro..city driving or highway bro?

i pump RM 60 also can go around 350 to 390, depends how my leg control sometimes..,with 50% highway 50% city... same AT 4918 also..., and is a 9 years old car..,

Yup, that's the one. Funny thing is, when I test the pin-out of the this unit, it seems to be in good condition. Can get around RM90+? I heard the main power window module cost around RM200+... Where you buy that? If RM90+ I might just buy it. But still, I want to open up the current unit and see for myself.

my mechanic told me that waja (4g18p) has 1 never can be solved defect, the ecu DO NOT has back up memory if power lost occur (eg. battery drained out) unlike other cars which have back up memory. so wht u need to do is to get to nearest authorised proton SC and ask them to reset your ecu and everything will get back to normal. about the grounding cable, it made different to my waja driving experience, only if you install voltage stabilizer as well.

been driving 4g18 AT (6 years old already), i usually get around 350km for rm50. but if dont drive rough, i can reach 400km with dat amount of money. dat was w/o any mod and petrol was rm1.92/L. if install VS n grounding cable, sure can get more mileage! *jz installed them*

After 7 years, finally settled my Waja car loan, it is a 1.6 AT 4G18P Waja anyway.

I think somewhere the absorbers are going to die soon, noise "nyek nyek nyek", changed once at 65,000KM, now is 103,500KM.

Any experienced sifu here can share how to mod the car to have more comfort driving experience? I don't drive fast, but just wish to improve the handling. Things like recommended tyres, brake pad, absorbers, voltage stabilizer, grounding cable, filter, strut bar, etc...

Is my first car, so now got a bit money to learn how to mod.

Take out batter also will reset the ECU lah

Don't have to go to SC, just drive the car around and it will recalibrate by itself.

Really bro?i going to change my battery soon as already 1year plus plus nearly 2year...what should i do when changing battery?just take out battery as usual and install back the new battery?will the ecu auto reset?and need to go back to the SC to ask them reset back my ecu?

i jus change my battery no long ago...no need to go for SC too~

you just take out the old battery and change to new battery as usual bro?or start the engine first and while the engine is running you take out the battery and then install the new battery?

When you installed the new battery was your car idling unstable?

btw which year car you drive bro?

Mine, battery died till have to change new battery(alternator kong back then) The proper way would be to install a new battery while connecting it to a live battery...so that the car's alarm wouldn't be triggered(not important)

Im using 2001 waja...8 years already...havent been to proton sc to do ECU recalibration. After driving awhile, it will be back to normal.

Have you ever realised that after driving for a constant speed on highway, then once exit after highway, the car tends to feel sluggish? it is because the ECU has been recalibrated to constant speed driving.
