REP issue after head swap
I just finished my tti install. We were trying to tune the car, ran into issues with the heads. So today I swapped a different set on put the car back together. Now it's always in REP. We've tried three different working throttle bodies. Different TAC module. Checked the grounds. Throws a 1120 and 1221 code. Checked another vette in the shop with the tech 2. Showed a lesser amount on tp sensor 1 than my car does. To sensor 2 is the same. Any help would be great. I'm at a lose and will continue my hunt as I can not figure our why less than a day ago I drove the car down the road.

You have most likely connected and disconnected the Throttle sensor/s numerous times.
Recommend that you carefully and with close detail, inspect ALL the FEMALE and Male pins and make sure that they not damaged. Especially the FEMALE PINS. Make sure that they are not spread. Mkae SURE that none of the wires in the back of the connectors are broken.
The engine wiring harness at the back of the manifold can also get damaged where it bends around the metak bracket at the rear of the fuel rail. Check that harness for damage/pinched wires.
