I'm riding along last night, hit some rough pavement and my check engine light comes on. I took it to my local mechanic to run for the codes and it came back saying PO420-Catalyst-Bank-1 and PO430-Catalyst-Bank-2. They say the problem is the smaller catalytic converters that will cost me $2000 ($1400 in parts) to get fixed. I have looked and can not find any catalytic converters for a 2001 Pathy that cost more than $210. They told me there is actually four converters on this truck. Suggestions? 87,000 miles so I'm over the warranty. Any help would be greatly appreciated......
