For now my wira 1tank can go around 400km RM80+ a tabk. So far so good now. Next month will go and check some issue. The car suddenly engine mati. Dunno why everything still on. Push to N then start back is ok.
My suspect is the fuel injection. Since if is fuel pump issue the car will goyang very kuat because hard to pump the fuel,but my car didn't have such problem. Will diagnose agn when checking.

I had that problem on mine also, it was the 02 Sensor, crank sensor & throttle body dying all at once...

Have you changed the fuel filter?

Nope, haven't chg the fuel filter.

Seems odd that all 3 sensors croaks at the same exact time

Wira update.

The machine say maybe is the throttle body issue. Might need to buka and clean it 1st. Juz a labour RM40. After that wait for thr result.

You can also check the plug to the air flow sensor. If its a bad connection there engine will die off.

After Cuci the TB the TB response is good. But when I terus tekan minyak rpm go up it suddenly have a laggy feel. Is like the TB open close open close feeling when from 2k to 5k rpm. The mechanic say take bsck to him to check. I think the worst case is the TB is going to die already. Hahahahaha
He also help me chg a map sensor on the speedometer now everything is fine. Juz need to settle TB issue only.

how's the idling? cold start does the rpm rise? when u shift from P to R is there any lag when engaging? then from N to D is the same?

The idling is ok.
Cold start Rpm is around 1.5k but will drop to below 1k once is warm up
P to R & N to D all are ok.

then can rule out torque converter and idle speed control unit. i'm too lazy to go through previous pages, your o2 sensor is ok right? hopefully the shop that service the tb can find the problem.

worse case scenario u might need to change throttle body. recon ones are around RM320-ish. used one would be below RM200. if your idle control unit is working fine, then u can just get the used one.

ya. coz the idle controller is damn canggih. got lots of gears in it. most shop will just ask u to change TB to recon one but actually the idle controller can be service. i hope you'll get your issues solve.
