Ok bought a 1989 Burb w/TBI , 5.7, 700r4 and 103,000 miles on it. Seasons changed and now I am getting a Code 32 - O2 sensor - I replaced it, and a Code 45 lean exhaust sensor. Is there something I am missinig or is there a common fault which would cause both of these to trip at once. The vehicle runs great, even when the service engine soon coomes on it still runs strong.
Anybody ??
Thanks
Steve
