Codes 1133 and 1153 Please help!!!!
Codes 1133 and 1153 Please help!!!! No acrchives!! Help...... I have a 2002 T/A with LTs and keep throwing these does after new O2s and all. I have read about exhaust leaks nearby causing these codes as well. The car runs rich as hell and where the header collector and cat back hook up is a band clamp and split pipe to squeeze together with clamp. I can see carbon or soot coming out about 3 inches from these band clamps and they won't tighten anymore. The O2s are only 2 inches from this soot. Could they be causing these codes? The soot also travels backwards? somehow against the exhaust flow and creeps out of this split? Please help me!!
