[QUOTE="SCGallo2, post: 16416274, member: 160791"] The bypass actuator is entirely mechanical, works off vacuum or lack of vacuum; I doubt that it would trip a fault, however it might cause other monitored conditions to be out of normal parameters, tripping a fault... I’m really not sure. The vacuum source is tapped into the upper intake manifold under the back of the blower, doubtful that you can see anything without a small inspection mirror and flashlight. I would double check all connections on the blower for a vacuum leak. The only other thing I can think of that I would do if i were having this issue is datalog THROTTLE ANGLE COMMANDED, THROTTLE ANGLE ACTUAL, and PEDAL POSITION to see your throttle input and what the car is actually doing. If these were too far out of agreement, I would think it would trip a fault. [/QUOTE]
