I have the far-too-common throttle closing issues, but ONLY during part throttle. WOT throttle (and less than say 20%), car works great. But, anything between 30 and 90% accelerator position, the throttle opens / closes violently.
I have had 2 tuners work work on this car with no success.
Anyone have any thoughts on:
changes to sensors or parts?
layout files to 'see' what might be causing the car to command the throttle closing / opening
