I checked again for any loose connections but didn't find any. But, when I started it again the check engine light was not on. I guess it just needed some time to reset itself.
Thanks for all your help.

P0107..manifold absolute pressure MAP sensor circuit low voltage
p1120..TP sensor 1 circuit-A
p1220..TP sensor 2 circuit-A
p1514..TAC system MAF performance - A
p1566..???? are you sure its not p1516 which is..command vs actual throttle position performance(TAC module) - A
Looks like something around the throttle body check for vacuum leak

http://www.c5-corvette.com/IPC_Codes.htm For a list of codes. Did you put the vaccume lines all on in the back? My guess would be a vaccume leak.

Check all the wires make sure everything is connected back together. Had mine replaced by the dealer got it home and the check engine light came on. started throwing codes. went under the hood and had to wiresthat were not connected back buy the dealer, reconnected the wires reset the dic no more problems.

I think I got that little tube. Boy was that fun!!! I had to pull the manifold forward about an inch to fit my hand back there. After I would get in lined up, it would come out after I slid the manifold back into place. That was a fun 20 minutes, I had a few choice words for whoever put it there.
