Was raining out Very bad and now vette wont run corretly
2002 Corvette Stand trans.
So a week or so ago I was driving home and it was raining out bad. I didn't think the water in front of my driveway was so deep but turned out it got onto my intake filter and into the intake. When that happen i shut off the car and pushed it out of the water and to a drive spot and pulled the filter off then started the car it spudder for a bit but then cleared up and ran fine for the night. The next day i started it up and the car threw a bunch of warnings and So i checked the codes .
P1120 TP Sensor 1 Circuit
P1220 TP Sensor 2 Circuit
P1221 TP Sensors 1, 2 Performance
P1516 Command vs Actual Throttle Position Performance (TAC Module)
C1278 TCS Temporarily Inhibited By PCM
I replaced the TPS already thinking that might of been the problem. I checked the grounding wires and cleaned them off. Also checked the TAC plug and cleaned it off as well. Please help me I don't no what to do next.

Unless you have the Factory Service Manual and a scan tester, you are going to have a tough time solving those codes.
If you don't have those items, you probably need to see a dealer.
if you do have them, start by reading the FSM's information on diagnosing those codes.
Know that some aftermarket air filter assemblies are prone to water ingestion when driving through standing water where the bottom of the front air dam touches the water. Water ingestion not only may damage the throttle bore assembly but may damage the engine itself.
I'm going to guess that the throttle bore and the ETC hardware has been damaged.
