Hey guys i am new here and not sure if this has been brought up before but i will take my turn asking. I just finish installing a brand new 350 crate motor. I put on hooker headers, magna flow high flow cats, and flowmaster 50 series mufflers. the headrers only had one bung for an O2 sensor. The sensor is a single wire. The truck is running super rich....really strong smell and lots of fuel coming out the pipes...what can i do?????
