ok, i will post here first and then start a new thread if necessary. i have welded in the new bungs. i swapped the sensors into their correct position and have new sensors in the post cat position with the original pre cat 02 sensors in place. the new 02 bung is welded into the primary of the 3 and 6 cyl iirc. i didn't look as closely as i should have when it was on the rack. i drove 100 miles and everything seemed fine, then "bling" on came the cel again. codes are 1053 and 1276. i have a new set of correct pre cat 02 sensors to install. what else could the code be indicating? is it possible that the new bungs arent allowing the 02 sensor deep enough into the exhaust gas stream? could that possibly cause the problem?
