2003 Chevy Silverado 6 cyl Two Wheel Drive Manual 91,000 miles
My check engine light came on. I took it to a mechanic that put it on a diagnostic machine. I dont know the codes, but he said that I needed a 02 sensor replaced & catalytic convertor. I could only afford the 02 sensor at the time. Now my check engine light came on again. Does my truck have 2 catalytic converters or one? Is this a expensive repair or should I best take it to a muffler shop for repair? I do not need a smog, just had a passing smog 8 mos ago for DMV.
