Hey I'm new to the forum, I have a 01 Suburban. I changed the 02,s and still the engine light would come on, but that's what the code read. Finally change the plugs and wires, great that did it right. Nope driving today , engine light comes on I start loosing acceleration then a small backfire. Get to my destination , sit for a while. Drive home truck is running fine, but engine light is still on. Please Help!!!!!

Have you checked the fuel injector? It may be clogged. A vaccuum or exhaust leak can be also a possible cause.

did you test the wires for current going to the sensors?
