So... In order to use my rear O2 sensors as the fronts, I repinned the PCM harness my swapping the wires. Same thing I did on my Camaro.
I called and talked to Geoff for a minutes a little bit ago. He wants me to get a timing light and ensure the coils are actually firing.
Also to unplug the O2's completely and remove that from the equation. Unplugged they'll they'll the PCM 450mv or whatever it is, instead if 0 if they've failed.
Then, check the plugs to ensure I didn't somehow crack one.

Hope you get those codes ironed out. Also double check all the ground straps as that is quite an issue for C5s on the Corvette Forums.

It's really all 3 codes that are baffling to me. How in the hell do BOTH o2's go out at the same time?
And the 0300? Multiple misfires? Why? New plugs, new wires...
Timing gun is on the way and I'll see if I don't have a coil that magically **** itself while they were off the valve covers

I'm still going to say what I said earlier, that you need new 02's. If it ran fine with them unplugged then bingo there Is your problem(or in the 02 wiring) that Would foul out the plugs like that also. Unless your wiring somehow got jacked up when you repined them.
Same **** happened to me when I did my H/C/I and exhaust at the same time. Car started stumbling and running like **** and my wideband was all over the place. Replaced the sensors and fixed everything.

That's what I'm thinking... But how the hell do I figure out what pin goes where?
I swapped just how you're supposed to I think.
25-26
28-29
65-66
68-69
Who knows. Maybe I screwed it up.
Only problem is the wire colors.
25 and 26 are both tan.
28 and 29 are both tan/white.
65-66 both purple
68-69 both purple/white
