this place deader than graveyard

so while waiting, bro you know who is good at tuning carb?

Hello guys, recently i just bought a 2nd hand wira with 4g91 auto transplanted. I am quite new to 4g series engine. Need to learn more from you guys. Currently i just got the car and encounter idle problem. It seems the idle rpm not stable. While in P mode, the idle is somewhere around 1k rpm w/o air con. Now when i open air con the rpm will fluctuate and whenever i engage a gear, such as D mode, when the car is not moving, the rpm keep revving between 200-800rpm, sounds like engine gonna die off. I research around forum and found that its common problem for wira. Many will say isc problem. Can i get it repair, or some suggest adding a ficd might do the tricks. Approximately how much i need to fork out to get it repair, Fyi the throttle body is mmc 1 , not vdo. another thing i want to ask is what engine oil u guys recommend for 4g91, to prevent the tappet sound in my engine block, so far I havent hear any tappet sound in the engine.

ok cool , btw powerzone also does it any idea if they are.good?

thanks sifu steven.. I really looking forward to know more about my engine maintenance. now i'm trying to fix the idle problem.. so far havent encounter any tappet sound.... Btw the what is the function of power mode transmission, i dont feel anything by leaving it on... cannot feel the difference.

Should put all these tips and tricks link on first page, with spoiler. Not sure if this had been done in previous thread, just gentle suggestion.

e.g.

ISC Step motor: 4G9X notorious Idling RPM problem... or something like that

Hi guys ...as I told u guys i buy a 2nd wira from used car dealer which successfully transferred the name... Recently i was worried about the car might be illegal due to i found this 2 marks ..




I'm quite worried that I might bought a welded car aka kereta potong. Can u guys help me on this matter? can I send to jpj for reinspection, because the dealer hired a runner to do the jpj procedure....

this should be visible to most Wira, I seen it before, i think....

for my perdana the cut point is lower. Not sure why is it like that though. Janji puspakom pass

hey guys, anyone remember 'radiostar alarm'?
what happen to them?

Yup you are right, I have no problem when driving in petrol mode.

Anyway, problem solved. The mechanic restricted my air flow by using sticker to block the airbox hose.
He explained gas mode requires higher electrical ignition,when the ignition system (ignition coil, plug, plug cable) is not in optimal condition (has been running since 2 years ago), my car can run on petrol smoothly without any problem, but will face problems like mine when running on gas.

So he has blocked the air flow and it's not the best set up for petrol (less air/ oxygen), but my car currently is optimum in gas mode. Problem solved.

so the company bankrupted?

i know but their specs for the price was really good.
plus there are many rebranding companies at malaysia like ninetology and duraplus.
its okay as long as their service and warranty is good.
alot of the no name china brands have decent specs and are cheap but anything goes wrong the shop won't help

For a 14 years old car, what do u guys think about my car interior?..

1 year only clean 1 time..

whoah....what specs 
everything yellow color 

INTERESTING!
lemme know when its completed 

Hi I have got a Wira SE 2004 model. Always been into ICE and but really wanna take care of the car engine and ride aswell.. Sifu sifu tolong ajarkan...

Thank you sifu .
What engine oil would you reccon?

Boss Steven, thanks for your in-put. However I can't transfer your in-depth experience into my skull directly, could you please clarify what of your mean by ignition is not advanve enough and misture is not correct?

I had not facing such problem (just the car is always under- powered) before my last changes of plug.

Now my car acts perfectly in gas mode, still observing the petrol mode (as I clocked most of my road time in gas mode, petrol is only used to start the car and before I switch off engine).

So are you indicating that the mechanic by restricting the air flow, he is effectively retarding the timing on my car? which is going to cause valves burn in later stage?

BTW how much is your friend's standalone ECU? VDO wira NGV as well? 

I guess it's a compromising method by restricting air flow and dual mapping on ECU would be the best solution   , but stand alone for VDO wira      let alone sifu/ master like you to set the thing up ...
