Discovered Limp Mode
First time I've experienced it, but I got a message saying "Reduced Engine Power" accompanied by a Check Engine Light. My biddy calls it a Checking account light.
Monitored all the vitals, didn't see anything abnormal.
Will take it to the shop in the morning, hopefully for a small issue. Has anyone had experience with this?

Mine did the same thing Friday about 2 hours from home, fortunately there was an Advance autoparts a few miles away and they checked the code. It was in fact the P2135 tps code, I made it home fine and had my local guy check it as well the next morning. The check engine light went out on it's own and I have driven the car over the weekend, but it's going to happen again right? The YT videos look pretty easy for changing it, however they were not LS3 motors, has anyone changed theirs, is it as easy?

This was the first time anyone on the forum has posted before correcting a typo?
It was obvious to me what he meant when I read it.
Looks like this will be another thread that goes on and on with few replies that address the OP's question.

UPDATE:: After some research on this forum, I focused on the Vitesse Throttle Controller. I tried recalibrating it 2-3 times, but didn't fix the problem. I disconnected it, and the 'reduced Engine Power' message went away, but still had a Check Engine light. Reset it with an OBD II scanner, and haven't had any more issues.

Although, it's nice to know I can be funny without trying.

That's the plan.
Mr.owc6 always makes an amazing spread. And when I say spread, I mean spread throughout the day. Usually a half-dozen courses or more. He won't let lift a finger.
It's awesome and strange all at the same time.
