I have A 2000 Chevy prizm with 1.8 4cyl. engine automatic transmission ac with 56,000 miles. Check engine light is on had it scanned at automotive repair center said the o2 sensors were bad ( bank 1 system to lean ) I replaced them both one on the intake manifold the other behind the catalytic converter. cleared the codes one day later the light came back on again with the same code. any ideas on what else could be the problem ?? any help would be greatly appreciated !!
