i just swapped a 1997 ls into my friends car. he took it for a ride put about 5 miles on it and it threw 4 codes. both o2 codes,speedo. and the E.L.D. code. I cant figure out what is causeing the ccdes but the alternator is also not cahrgeing. i had it check at autozone and they said it was still good. Any help would be great. thanks.
