Hey all,
I've been having a problem with catalytic converters. This is the second time I have taken my truck ('02 Double Cab V6) in for trouble code P0420, Cat Efficiency Below Threshold, Bank 1.
The first time this happened was at 54,000 miles and they replaced the whole works. Now it's happening again at 72,000 and they have to replace it all again. (Fortunately under warranty!!!) I installed a Jardine Cat Back exhaust around 30,000 miles, and have found some hit-and-miss info on the internet of other Taco owners with the same problems, after installing an aftermarket exhaust system.
Can anybody verify this?? Should I go back to the stock exhaust, or am I just having bad catalytic converter luck??
Thanks in advance,
Beave
