Ok so I got a 1998 Chevy Silverado. My friend just bought a CarMD so i decided to plug it into my truck for fun. It came up with the Codes P0420 and P0430. Which means: Catalyst System Efficiency Below Threshold (Bank 1) and Catalyst System Efficiency Below Threshold (Bank 2). What does that mean and how do I fix that?
Also Im trying to figure out what generation engine I have in my truck. Its the 5.7L 350 but I cant find anywhere which generation that is. Im trying to figure this out because I want to buy a engine from a salvage yard, rebuild it and put it into my truck. This is the book im looking at: http://www.amazon.com/How-Rebuild-LS-Engin...n/dp/193249460X
Also, do I have to find a 350 engine from the exact year truck I have or can it be from any Third Generation Chevy or GMC truck?
Also, do you know if there are any performance rebuild kits for that engine?
Thanks,
Max
