Hey guys,

Been trying to diagnose a stumbling-during-acceleration issue on my FR-S for a long time now. Finally got around to looking into the TPS. Questions for you:

1. If car is off, key is ON, does your throttle body emit a loud buzzing sound? Because mine definitely does.

2. If you gradually depress the throttle (car off, key ON), does the throttle plate "jump" open when you've reached like 25% throttle on the pedal? Because mine also does that, and doesn't seem normal to me.

Thanks!
