Message	caused by the TPS Idle Switch going back and forth between 15 degrees BTDC at Idle On, and 40 degrees Idle Switch Off. This happens almost immediately, like falling off a cliff. 15' to 40' within 25 rpm difference and with the throttle butterflies, and TPS barely moving. The 'bucking effect' is simply enhanced by any drivetrain slop; but it is NOT the cause. The Idle Switch is the cause. _________________________________________________
