Big Vac chamber on the TB is the contraption that causes Limp Home's heavy throttle.
IF you look deeper you will find the Throttle body has an Electric Motor which runs the Throttle plate.. based on the pot attached to the throttle pedal. Drive by Wire means exactly that.
If you remove the Vac chamber hose and plug it you may get a passable throttle action.
Won't solve the driveabilty issues though.
TCS failure largely sent ALL tcs fitted 9000's to the crusher... years ago.
Few wild ones remain... ponder that for a moment .
Red white pcv valve is critical to TCS.. be Sure it's working as intended.
Often those were the root source of TCS failures.
Don't be fitting a substitute part either.
