Yaris 1.3 throttle judder

[Leo6596]

Hi all

the missus has got a Yaris 1.3 sr,  it has some good running days and bad, the main problem is if you give it sharp throttle, the car tends to judder quite badly till it catches up with its self, it’s had new filter and oil, spark plugs and air filter,  MAF sensor looks clean, just wondering if any has experienced this before and what it could be link to?  

 

cheers

The EGR valve may be carbonned up. Check that.

Oh right ok, does it make a difference ours being a petrol? , just as I thought diesels only had egr’s

Some models, whether petrol or diesel, have EGR's - for example the Toyota IQ, which is petrol only.

Thanks, managed to sort it now!, turns out after cleaning the maf with contact cleaner for an hour it’s completely resolved it, it’s ran the best it’s ever been since we’ve had it. Cheers
