has anyone else had any weird problems with the acceleration seeming to pause slightly jsu goin into the vvti at 5k rpm.... really annoying cant figure out whats up....

Sounds like your MAF sensor mate, very common problem on Altezzas. Happens to most of them...

If you do a bit of searching you'll find a guide to cleaning them (doesn't always work, sometimes need replacing)

Was told on here that the pause is normal. But as Dizz says cleaning the MAF may improve it. A new MAF is about €100 from Mr T

same here guys i just lifted my tezza 2day.

i thought it had lifted dirt from the tank but ive driven about 300 miles so it would of cleared by now.

sometimes it jurkes like its miss firein' or something, but not all the time.

then when i hit about 4k revs it like, dies down abit then the VVTI kicks in when i hit about 5 - 5.5k and goes well from there on up the revs

its so annoying!!

would toyota be able to say what it is? coz i have 3 months warranty on everything

yep sounds like the airflow meter, mine was f*** and was kinda spluttery before the vvti kicks in, think i paid around 150 from toyota for it, seems to be a common thing with them

Now that you mention it.. If I put my foot down suddenly in lower revs it splutters a bit for about a 1/2 second before applying power, but it doesn't bog down after that. I just put it down to the ECU not being happy with the petrol over here and lived with it. I wonder could it be the same problem?

- I was looking for posts on how to clean it, but didn't find anything detailled. Found this on how to do this for a Mazda, I assume it would be similar enough to the Altezza?

mine tends to do it at the 100km mark if u go over it slowly she gives a bit of a jerk for a few seconds and then stops doing it..just thought that it was cause of the petro over here??

hi guys,i have the same problem and was putting it down to the petrol,where is the maf sensor on the car.
i noticed on my car when the temp gauge hit 70 the car starts to shake and it loses power for a few seconds then when it tips over it the car runs perfect.
