Modes c5z limp mode help
I just had my vette tuned. Now once in a while when I’m coming to a stop the car goes in to reduce power mode and I also get active handling message. Once I pull over and turn off and on the car everything goes back to normal. My car has a stroker ls2, heads, cam, lsx102 intake, 103 nw tb and other supporting modes. Here are the codes I pulled
P0103 P1431 C1221 C1222 C1248 C1278 C1281 C1287 C1288
The car has only 50k miles on it and less then 1000 on the new built. Any help would be appreciated.
Thanks in advance

P0103 Mass Air Flow Sensor Circuit High Frequency
P1431 Fuel Level Sensor 2 Performance
C1221 & 1222 are front wheel speed sensors
C1248 is not listed in the 2000 service manual index
C1278 TCS Temporarily Inhibited by PCM
C1281 Steering Sensor Uncorrelated Malfunction
C1287 Steering Sensor Rate Malfunction
C1288 Steering Sensor Circuit Malfunction
If it was working fine before the tune I'd start by going back to the stock tune and undoing any work performed to support the tune.
Verify your battery is fully charged before you spend much time on it. Low voltage does all kinds of weird stuff.
