anyone interested to buy toyota cars? drop me a pm
highly discount

Anyone interested to buy second generation of Vios 1.5G (year 2004), please PM me. Everything in good condition except the body paint ada calar calar sikit. Engine wise, everything good. Maintenance done in Toyota Service Centre.

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.

mind sharing how old is your car and what mileage?

2008 dugong model n mileage only 58000+ only, mine very low mileage becos mostly to office n back becos i got another car

a dirty throttle body?


maybe air filter is too dirty and not cleaned for some time hence dust messed up the sensors.

hi..

can someone tell me what is the different between vios type J , E and G?

Bro, my KNN air filter clean every 8-9k n throttle body clean every 10-15k interval

meaning not advisable to change to KNN?

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

i did my research on K&N filters before purchasing them.

not a single car problem was reported to be caused by the filter.
only research papers stating that its not blocking 99.9% compared to the stock ones.

but hey, if you wear a mask that blocks 99.9% of particles, breathing ain't gonna be any good either

I'm pretty sure a reputable company who has been doing filters for so many years knows what they are doing

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

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.

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....

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

yes bro.

increase hp.
lower FC.

how lower is the FC still depends on the foot though...
as revving at low rpm is much easier

The SA call me at 3.00pm n said after changing the 2x o2 sensor n MAF sensor its still the same n have to leave it there to check for another day. Worry they might charge me for the wrong part they change, n not sure when they can verify the problem

even Toyota SC themselves could not pinpoint the problem of their own car

better scold them bro, and ensure the sensors does not need to be changed as it is not the cause of the problem.

or you're gonna get a huge receipt from them

VIOS trd pre-imp unit, discount RM 3988! wow:) pm me

You r right bro, their own brand car they cant repair then where r we going to repair. Secondly i am going to make so noise there 2moro.

waiting for more updates today, good luck bro

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.
