And did those spark plugs show any sign of running rich?

If you do your CEL will stay on and you won't pass inspection. That is if your state has them.

Have you determined which CAT is bad?

I'd suggest you look at the fuel trims to see if that's what took the original CAT out or you might just be setting yourself up for a series of CAT replacements.

You really need to pay a shop to diagnose this for you. Doing it in the parking lot isn't very effective at this point. $80 an hour is cheap compared to what you have spent and are about to.

Yeah your right but it's in poplarville,ms a small town where there is barely anything around, surprised they had an autozone!!! That's y I've been doing everything from the parking lot. But you are right I have to find the nearest shop and get it towed there. If they don't tow it on their own first.

No, no signs of running rich on the plugs. And I'm not sure if he checked fuel trims. I know when I called to have him come to autozone with the high dollar scanner I described what was going on and he said clogged cat immediately. Then he got there and did his tests and just told me to have a shop change the plugs because I have 122,234 miles and their probably on the original plugs. Not to do it myself, which I did anyway with no problem luckily. But he did get under and was knocking on the cat to see if he heard anything. And advised me that just because he didn't hear anything doesn't mean that's not the problem. He said get it tuned up and go from there. I'd think this 2000 dollar scanner could point to the exact problem but it didn't, he just gave me an option of two things that's spark plugs or the cat.
