Experts k lia Challange ;), Passo vibrates on idle IAC Valve or Mount Rubber?

[yasiraza1185]

Salam Folks,
when i start my passo in the morning it does not vibrates on P and also when i put ir in D the vibration is very less, but after driving it 2/3 Km the vibration increases on idle, so what do u guys think it is mount rubber problem or it it IACV(idel air control valve) problem,

[yasiraza1185]

one thing is confirmed, it is not a mount rubber problem, yesterday got it checked, what next then, btw where is this iac valve located,

[alee1]

maybe its iacv prob then

[yasiraza1185]

but where it is located under the hood

This engine would not have an IACV, it uses an electric motor throttle. It needs to be checked on a stream scanner - the motor feedback circuit could be lazy.

thanks brother, tomorrow i m going to visit toyota dealership, i will tell u the details whatever they say, can i have ur e mail Xulfiqar i have got the CCa data, i want u to confirm it, thanks

if i change the spark plugs and go for irridium plugs will it improve the situation as i read some where that
[h=5]Smoother Idling[/h]When an engine is idling, firing can become particularly bad. Because Iridium Power plugs have a low required voltage and high ignitability, sparking continues to work properly during idling. Whereas normal plugs have highly variable revolution counts, Iridium Power plugs maintain very smooth idling. Also, because combustion is good, the explosive energy raises the revolution count.
[h=5]Improved Engine Performance[/h]Iridium Power spark plugs enhance the performance of an engine. Acceleration is improved when compared against normal spark plugs.
[h=5]Decreased Fuel Consumption[/h]When Iridium Power spark plugs are used, accidental fire and misfiring rarely occurs under various driving conditions. Therefore, combustion is extremely good. In turn, a healthy engine can be maintained and fuel consumption improved.

A friend who owns one had the same issue. Said the throttle body needed cleaning.

[yasiraza1185]

what kind of cleaning, cleaning with spray is enough or throttle should be removed for cleaning, pl advice

you can use the forum to send me a PM or even email. btw how would I confirm it, you are part of Exide Batteries in Pakistan - if you are providing data you are the only person to confirm its validity.

what you are explaining about spark plugs is for engines that have super wild cams or extreme lean burn, Changing the old copper ones with any precious metal will not change the driving experience unless your original items were worn out. In that case - you restore the "original performance"

i got the throttle body cleaned at toyota dealership Peshawar, the problem still exists.............

bro clean ur throttle body and also choke sensor with cleaner and open sensor screws and clean whole sensor rotating ball it needed bcz same isue with me abt passo bcz its engine type is different from vitz is calibrate pedal wireless electronic throttle with CVTtransmition but passo is DBW drive by wire and super ect i transmit ion it has TPS and Choke sensors on throttle body its must be clean and refresh from Toyota own scanner.
