Question

1999 Chevrolet Camaro Z28 5.7L with engine codes P1657 and P0300, what does This coed really mean?

Answer 1

P1657 1-4 upshift solenoid control circuit

P0300 Random misfire

P1657 is not used with this transmission what you have is 1-2 shift solenoid , 3-2 shift solenoid, 2-3 shift solenoid,As for random misfire code P0300 this can come from false air such as a vacuum leak to low fuel presssure, Randmom misfire is more than 1 cylinder that does not contribute to engine performance
