Here's the deal, i bought the car 2 years ago and it passed smog fine with the catalytic converters installed. They were taken off and replaced with test pipes for 2 years of driving. Its time to smog the car again and so a week ago i put the cats back on. I've only driven it for a few miles today and then straight to the test only center. AND IT FAILED... lol
Now i'm wondering if the cats went bad after 2 years of non-use or its only because i didn't drive it enough yet to get the cats up to operating temp? I drove it a good 10 miles though, and I dont think it takes that much time and heat to get it going, correct me if i'm wrong.
Next, if you read the test results (the smog tech guy told me this too) you'll see that it looks like the cats aren't working at all, everything is off the charts as if it was running open exhaust.
I dont really want to buy a new set of cats but i will if i have to i guess. Looking at the chart and the situation what do you wise owners suggest?
As additional info i'm running DC headers with a GTLW. 93 model, no CEL no other problems.
