Hi,
It happen to me today.
Mine is 4AT 2006yr.
It happen when I stop at a triffic light junction. The car didn't stall but the rpm drop till 400, normally abt 800. The car no reaction when I press the accelarator and the engine indicator light turn on.
I turn off the engine and call a friend for help. I restart the car after awhile and the car back to normal.
I thought it fine and I start to drive. And it happen again when I stop at the next triffic light.
My friend who came by to help take out the piping connect to the throttle body and use something to poke the valve. He said the valve might be jam. I try to restart the car agian and this time the car back to normal but the engine indicator stay on.
I think I'll send to TCM Ubi tomorrow.
BTW, by using the computer thing that plug to the car, it will show the fault right?
Hopefully, they can find it.
