I've been throwing an SES light for a while now but I finally have HP Tuners scanner to find out what the problem is. I forgot to copy it down exactly but its definitely one of the following:
DTC P0420 Catalyst System Low Efficiency
DTC P0422 Catalyst System Low Efficiency Bank 1
DTC P0430 Catalyst System Low Efficiency Bank 2
DTC P0432 Catalyst System Low Efficiency Bank 2
Is this the dreaded O2 code everyone gets for putting on a high flow cat or is it at least related? It only came on about 20 miles after I had my Carsound Cat put on. But at the same time I had my PCM programmed by TSP and they erased all the O2 error codes that should have been thrown by the new cat... I'm very confused, can someone help me out so I can go about fixing this?
