Honda DBW Throttle Closing

Hi guys,

I recently got an issue with a client car Civic Si with ZDX throttle same as the J37 Throttle, the car ran fine at lower rpm but as soon as you step on the gas and get to 8000 rpm the throttle closes and the engine light comes on. Code is p2101. I somehow got a temporary fix by limiting the throttle plate opening to 90% anyone else got this issue? is there a fix to this?

Thanks.

I assume you've seen this thread with some suggestions...
