Working on 2000 C5 Corvette.

I'm getting a couple of codes on the Vette. They are: P 1120
P 1220
P 1516.

What do you think I should do. I Pulled off the Vaccum lines at the throttle body and the one that's on the pass. front of the intake. I capped them off. I cleaned the air intake boot, and wipped out the inside of the throttlw body. And now, my car is in "Reduces Engine Power" and I have these codes... Please help. I just want my car to run...



Thanks

Reset the battery??? On the C5 you can go on the driver's display, and run through the codes and clear them if needed. Are you just talking about clearing the codes..?

your codes are all related to your problem and i sudgest if your gonna work on this car to get a manual.disc. batt and clearing codes DOESNT FIX THE CAR . your codes are TP and TAC data that is out of range. it is a long diagnostic tree that must be followed. you can try the public library for MITCH. manuals. if i tried to type the procedure my one finger will fall off,i have the manuals. for what its worth all man. start with ,check basics eg. every thing plugged in ,air leaks,fuel psi. a dvom maybe use to check TPS volts but with out specs.........
