Ran Seafoam last night. Car idles and hums nicely. Decided to Hail Mary it and installed the tune (after Seafoam). Car runs butter smooth. Took it out this morning for a spin, no misfire (according to Forscan) but ETC failsafe kicked in after some spirited driving, with those codes. ETC failsafe only kicks in when revving high. Does NOT happen on idle. (Note, I'm using the tune to coax out the failsafe). Any ideas? P2107 is Throttle body code. Bad plate motor? Bad position sensor?
