Help with stock EFI

Thanks for the info. Took the car for a couple shake down runs up and down our road. Doesn’t run too bad, shifts a little fun for 2nd to drive when shifting manually. Got a few noises to figure out, but thinking most are exhaust related. One thing that has popped up that I find odd is that the back up lights are on in every gear except part. And suggestions what might be causing this?
