i just did a swap.
92 auto dx
95 gsr motor
i had to extend the o2 sensor wiring longer.
i am not sure if i was getting the code before i extended the wiring but not after i cut the 4 wires and add lengh to them i get codes 1.
i then took out the o2 sensor and swapped it with another one i had, i also stripped all the tape on my extension to verify i matched the colors correctly, now i get a code 41. i did notice there was a white wire that looked shielded. when i extended it i did not shield it. is this necessary, does anyone know what else could be wrong here? thanks in advance.
