First, check for error codes

But I'm guessing you need to adjust the TPS

Back when my Supra was N/A (I've tried to rid my memory of it) I had the same thing and it turned out the little vacuum hose that connects underneath the big hose that runs from your throttle body to your afm was not connected properly. Exactly the symptoms you describe.

you know about a week before it happend i had new gaskets for the upper intake replaced . good to hear it could be something cheap. i had two mech. say the motor was tired and ready for a rebuild. when in doubt turn to the forums you mean Air-Fuel Meters right
