2012 Yaris 1.33 - Idling problem

5 posts in this topic

Good morning everyone,

I hope someone can help.

My wife's 2012 Yaris 1.33 petrol has some problem with idling. It doesn't have any issues with power and pulls as it should. Hovewer when engine is warm it's juddering on idle, rev-counter goes down a bit and back up again and you can feel the entire car moves a bit. It doesn't keep the steady revs on idle. 
The car only covered 31k miles so I don't think it's the spark plugs as those are long life ones and should last at least 50-60k if not more. 

I'll be very grateful for any ideas. 

Kind regards

Might be worth checking and/or giving your mass air flow sensor a clean:

Already did. Took it out today and it looked as clean as new but gave it a clean with WD Contact Cleaner anyway. Made no difference :(

Ok, at least you can tick that off your list. Contaminated fuel filter possibly.
