My engine light was on and I checked it and it was the o2 sensors were reading too rich. So I got on here and they suggested to change spark plugs with ac delco, and I did. It went off for a while now, and just yesterday it came back on, this was right after I cleaned my air filter. Its a k&n cold air intake, but I did not use too much oil. Any suggestions?
have the same problem?
