I've been slowly getting my 98 K1500 back the way it should be. Love the truck, so it's been pretty fun so far. I recently replaced my downstream oxygen sensor, cleared that code, but now a couple days later I got the code P0430. From what I've read it's probably a bad cat, but I don't have one. . I see it can also be bad upstream oxygen sensors, a leak (which I don't appear to have) or maybe I need a sensor extension? Just wondering if anyone else isn't using a cat, had this problem and found the solution.
Great site by the way, helped me out alot so far.
