def. sounds like a TPS kind of problem

 

an update to the stalling problem...

some of you may have read that i have had a recurring stalling issue on my xB. on probably seven or eight occasions when i have exited from the freeway, the car has stalled out towards the end of the deceleration cycle. to provide background, i usually downshift from fifth to fourth to third gear, and then for the last 20 mph or so either push in the clutch or put the car in neutral so that i don't stall out. i've been driving stick for 18 years.

after four trips to the dealer--two where they've sent out a scion factory "specialist"--they have been unable to diagnose the problem. each time they have only kept the car for a 24-hour period.

last sunday the car stalled out yet again after about 20 minutes of driving. the tank was full, and the car had been warmed up before it
had been driven.

i called aaron at scion corporate again to notify him that the problem had occurred again. now we are at the point where his superiors are now recommending that scion buy back the car.

we'll see what happens. i hope they do me right on this.

 

aren't they supposed to buy the car back after the third time of the same recurring problem? Not the fourth? Anyway, I hope you get the new lava color if they buy it back from you. :D

 

andergtr...

it can be just a simple little overseen thing...

Let me put my 2 cents in..

A few weeks ago i went to get gas at a station i never go to. my xB was acting weird for a few day. the idle kept dropping like it wanted to stall and actually did stall once while in neutral. I could not think why.
i got gas at a few other placessince then and its been fine.
I traced it to being bad gas..
Anyone ever had the same problem?

 

i will just about bet my life that they need to replace the whole throttle body (sensors and all). This is the same problem someone else had on a matrix and that fixed it. that persons name on matrixowners.com is pandrus. my dad changed out his throttle body and it went away and he is happy.

 

i've filled up all over the so cal basin, using arco, unocal 76, shell, mobil, chevron, texaco, and exxon brands. it hasn't been specific to one station or one brand.

 

thanks to all for the replies.

aaron from scion called and said they are initiating the buyback of my current xB and are finding a replacement for mine.

i am very happy that scion is going to swap out the car. hopefully they will find the cause of the problem using my vehicle as a case study.

i've already heard from two others who have had the same problem. maybe scion will be able to find a fix to the problem.

 

check the iac.. ive had the same problem working on our scion
