Trouble codes?????
The First:
U1300- It said manufacturer specific code. Looked it up and it said (class 2 data link low).
Number 2:
P0446-Evaporative Emission System Vent Control Circuit.
So...does anyone have any idea how to fix those?
Thanks for the help.
The second one, you should check to see if your gas cap is lose, if its not then you might need to go buy a new gas cap. This code usually means that your gas cap has gone bad and leaks air or its the evap vent valve located on a line that goes from behind/ next to the ls1 throttle body to the passenger side towards the evap canister
