98 Accord 3.0 v6 with Codes P0420 & P0430?
I'm tuning up my 3.0 v6 and coming up with the current codes:
P0420 catalytic converter deterioration
P0430 catalytic deterioration
What needs to be done to eliminate these codes?
The car runs good with 140,000 miles.
Thanks, Concerned Speeddog

do a simple temp test on the cat you want to see 500 deg's on the inlet and outlet side. make sure the car is warmed up and under normal operating conditions.if the temp reading is 100 deg's less on the outlet side then time for a cat.
also make sure their is not any system leaks in the exhaust before the cat.
