bad o2 sensor or even removing it will only cause the CEL to light up (this will give error code), it won't cause engine to stall
since u mentioned no code before, doubt it's the culprit
what's the symptom before the engine stalls?

Is the batt healthy and has water to drink if necessary? Are the batt contacts clean and free from white deposits?
Because Maivee has this V sense on batt, if batt disconnect more than 10 sec it auto dies off.

no symptom ...if die ..just die like that ..like turn off key ..

bat condition in good as check by 4man..

thanks ...

dash, radio & ac all gone? or just engine only?

dash ..all logo icon lights up ..just like turn key to 1step b4
crank to start ..

radio ..ac ..no noticed off if remember correct...

thanks ..

bad ignition switch?
since no error logged and car restarts fine

not sure...but after changed o2 sensor ..engine off suddenly not happen yet...

thanks ...

Had the same issue. The culprit was bad alternator. My mechanic got it refurbish. No issue until now.

can describe a bit how the problem happening?


thanks...

Seem like u found the reason. Try driving that car for a long trip to verify.

ya ..ya ..the 4man drive long distance..he told no suddenly engine off ...

after many days drive ..still doing good ..
still monitoring ..


thanks ...

Done. Seremban - Kuala Kangsar. No more issue.

Fuel pump, happened to me, few times, b4 it totally kong

Should give her a car wash as present

i meant ..b4 changed ..car hard to start ? drive got sound ,
.....or just engine off tiba2 in driving?
then easy to star again the car ?

fuel pump , so car easy to start every time ?
engine stop while in driving? then easy to start back engine.?

thanks ...

First thing you need to do is change pomen. O2 sensor is the last thing to check for engine suddenly dying. Worst case for O2 sensor issue is high FC.

Did the pomen even check the fuel pump? Or the fuel injector clogged?

If alternator issue, it can easily be checked with multimeter.

However, if the issue really resolved...then I need to learn more.

FC like usual..not really monitor it ..
4man no tell me they check or no check for..fuel pump ..fuel injector clogged...

battery and alternator they checked ...no problem ..

do u think O2 sensor wont caused car engine suddenly dying?

till today still good...

actually the O2 sensor was faulty with engine logo light up ..4man asked to try see engine off happened or not ..if wont happened then will change new O2 sensor ...

thanks ....

update...

after few days...today happened ...car no engine off but dash board got few icon light up ...but not sure which one ..press oil pedal..car can moving ..the dash board light turn off ....

U already change the spark plug and plug/coil cables?

not yet change by 4man...
