ETC Failsafe mode!!

[DGLS04]

Ok so I have been searching the forums and have a couple of ideas of what the problem could be, but I wanted to get some input from you guys. I have an 04 ls V8 with 70000 mi. My problem has just recently started with the hot weather, it seems whenever I push the car a little hard the ETC Failsafe mode turns on. If I drive her gently it doesn't trip the failsafe mode. I pulled some codes: P2107, P2110, P2104, P2112. What do you guys think? Coils? ETC computer? Any help is greatly appreciated, thanks!

Me personally, I'd pull the throttle position sensor off and visually inspect it. Maybe pick a spare up from a boneyard, it's a super common part. It's $25-$40 new depending on where you shop. If you do nab one off something else to test, here is the vehicle list that uses the same TPS:

My '03 has had this issue three times. Every time it was a passenger side coil.
