This morning my car suddenly jerking n when moving slow press throttle paddle feel like no power at all, n send to Toyota service for checking n was told the 2pcs of o2 sensor n MAF sensor spoilt. Need to change n cost RM1800+ n not including workmanship. Wonder why 3 sensor at one go. No choice n have to place order, 2moro only can arrive the spare parts, Hope everything will be fine after changing.Anyone facing this problem before n why the sensor so expensive.

wah..really bad luck... do you have any engine check light? how is your car FC doing before and after replace the 2 O2 sensor and a MAF sensor?

MAF will be spoil in few ways like over oil your KNN filter, use the wrong type of cleaning chemical to clean your MAF sensor or damage during cleaning.

it also could be your throttle body electronic chip damage.

the price is about there the 1 really expensive is O2 sensor.


[quote=Dickong,Sep 4 2012, 06:12 PM]Bro, my KNN air filter clean every 8-9k n throttle body clean every 10-15k interval

[/quote]

wah you really clean your filter and throttle body, have you check how long can a KNN filter last and how many time can be clean? as we know nothing can last forever....


[quote=kenji1903,Sep 4 2012, 06:28 PM]meaning not advisable to change to KNN?

[/quote]

can be clean but during oiling the filter maybe over do it....

Maybe u r right regarding the KNN filter or the stupid SA simply trying on trial n error becos i remember i ask him after changing the o2 sensor n Map sensor, is the throttle going to be normal, simply answer maybe n not sure. WTH

yes there dont have correct answer for this it could be your throttle body electronic chip...... before change do SA show you the error code that cause your engine jerk?

some time there dont have strait answer for your problem.



[quote=dtna7,Sep 4 2012, 08:51 PM]i did my research on K&N filters before purchasing them.


Bro are you sure you did not "over-oiled" the filter?
it has to be completely dry before placing them back in again

what i did hear was an over-oiled K&N screwing up the sensors though

do update us if you found out the cause though, its gonna be real helpful as a lesson for us to prevent this costly replacement

you are right but filter like this do the increase power and FC?

hope for the best but i think could be long way to go....

What is the error code? do they show you?
the same few question i ask before....

looking at this it could be throttle body, timing sensor.

For manual user this is normal issue even when u use good GB oil some time very hard to enter 1 gear and reverse gear.


Good info..... notice this if idling RPM not smooth this is not only happen to some vios but also some nissan owner as now days most of the car maker use drive by wire technology .... as inside the throttle body chip is damage or the motor is damage....

Good info..... i cant comment much on RON 95 burn hotter compare to RON97, for my scangauge info after some testing both read about the same but i notice 1 major different is but both fuel on the ignition timing is different RON97 ignition advance time is less compare to RON95 maybe this part it kill our ignition coil...


Here are some info to share.
Fuel injection systems

BHPetrol of

What is the horsepower of CR-Z gasoline engine only not the combine with electric motor.

looking at 124ps CR-Z it had a hard time pull away from my sleepy milo tin

guys Any one had change the water cooler liquid? some of the workshop notice this new cooler from toyota red is deteriorate....

some time we dont need a bigger car... tested customer car... kelisa... small fun corner can whack but maybe i push abit too far...haha

Inspire tested the 2.0 nice car if it was manual and weight able to reduce 200kg it will be fun to drive ... just had a feel chassis abit heavy...

Can i like will be Megane RS 250 cup fun to drive, more you dare to push more fun best part is suspension is comfort not as hard as civir Type R or even DC5...

bars help you in some part but suspension is the next level

just change my spark plug this time i down grade from OWS iridium plug to Bosch Platinum IR Fusion plug.

This bosch only notice smooth power less knocking can feel power output maybe same or drop abit still doing testing on FC.

wah some thing when wrong.... check ur air filter? mine 2 years plus about 100k FC still about same between 530km ~ 550km....

now doing some experiment hope can reach 600km before blink.

i call it more fun....


yes can tested.

this is my round 2 testing i have done 391km with only 22.1 liter of fuel.

this mileage is 70% highway 30% city driving condition between 10am ~ 3pm no mod did just change bosch spark plug. Speed follow most of the road speed limit but on highway few time push from 110kmh to 200kmh..... hope before end of this week able to archive 600km overall.

Sh@rty,
How much for the switch, is it both button function?


Kenji1903,
I have add some diy lube in my petrol still adjust the ratio to gain mileage.

just finish testing, finally able to archive 589km max mileage as i earlier target for 600km before blink ....my driving condition is 60% highway and 40% city road between puchong, PJ, damansara...

how i able to archive this is by our petrol mix with 2t motorbike engine oil, the base line mix is on the average is 1 litter of petrol x 2ml of 2t oil.

Then our vios use 42liter petrol = 84ml of 2t oil.

in this test 1st or 2nd time will not notice any different due to it need time to clean the combustion chamber carbon that built up since the 1st day your engine came to life.

Im still continue to adjust this ratio hope to archive better result. For hp result pls dont ask how much it will gain in Dyno test run cause this is not a power test but it a mileage test.

my car is stock with clone air filter, bosch platinum ir fusion plug, Amsoil AZO engine oil 0w30, my wheel is stock steel rim 14' xm2 tire just for this testing.

yes you can buy at any Spare part shop but some time you need them to special order.

becarefull guys some product their acid level is very high it may cause glass blur in long run.


thanks next service will update spark plug condition....

look like good offer last time i got it around RM 160.


you can try LYT Auto market thread, mudah.my or drop by sunway area, look for PP material good built quality.

this is a normal issue for J owner, buying a J spec there is 2 spec that is 1 look for a manual car or 2 wan to own a vios but cant afford higher spec end up buying a base model.

other model better.

Kenji1903,

that was different range la.... sure better this is why at some stage Europe car is better then asian can.... Understand that the new Kia K5 also very good as their standard is to match European level.

New update,
been using 2t oil mix with my regular RON95 and on average able to archive range 570km~590km for average city driving, from my scangauge reading water temp very stable compare last time.
