Apparently, there are 2 catalytic converters. One in the front and the main one? Took it to a shop and I got pulled a p0421 error code.
Mechanic thinks it's the cat and not the O2 sensor? I guess i'll take his word seeing how I have over 180,000miles on my car.
I'm looking on Rockauto.com cause i need a replacement but i'm a bit confused. Are there any words or notations on the cat that states it's the front?
Better yet, anybody know of any other site that has it for cheap?
