P0202?
I was running the car pretty hard on a road course yesterday, not for very long though. We'll say 12 minutes and everything was fine. Drove it 30 minutes there, 30 minutes back and then went to shower and get ready to go over to a friends house. I started the car and saw a CEL and got the code P0202. I cleared the code and nothing came back up for the rest of the day, drove it in 2 30 minute segments and a hour long segment. Today I start the car to pull it out of the drive way to wash and the code appeared again.
I don't notice any issues with the car other than the code will appear sometimes on start up. There doesn't seem to be any loss of power or anything unusual going on, so I'm not sure what I should do at this moment.
Car is heavily modified: built ls7, built trans, head/cam, yada yada. 2006 z06 w/24k miles.
Any help would be greatly appreciated.

P0202 Injector 2 Control Circuit ECM
Pull the fuel rail cover on the passenger side, pop the connector off the first fuel injector towards the radiator on that side of the motor, clean the connection and the injector connector, a dab of dielectric grease, and plug the injector connector back in to the injector.
If you get the code again, then start tracing the wiring harness back to look for a loom burn through in the wires from that injector connector, or maybe even the injector is going bad (swap it out with another one in another location, and see if the problem follows the injector).

So I cleaned it and put it back. Still popped the code. Looked at what I could of the wire since it's all wrapped up and didn't see anything that looked bad. I swapped the injector and unfortunately I tore the o-ring that goes into the fuel rail.
I set all my stuff down and figured I was done for the day since the ring was torn, but....
Then I remembered I had some old c5 z06 injectors and realized the o-ring on it is the came as the c6, swapped it on, buttoned up the car and started it. No code. Shut it off and started a few more times and there is yet to be a code.
Very strange!

Loose wire connector withing the plug connector that solve it self by you fiddling with the injectors/connectors, or the something funky of the one injector and connector plug for bank 2.
Bluntly, it a C6, and have seen stranger electrical gremlins pop up from time to time.
