I'm going to start with the simple things like new plugs and wires, what's a good brand of plug and plug wire?

Autolite or Motorcraft.

I hope it's not the coil pack, those things are very expensive!

I've used the Autolite and Borg Warner. The Borg Warner wires seem to "snap" on better than the Autolite. Just my opinion though.

Well, that didn't last. It's back to the same thing although now the SES light will sometimes flash, what does that mean?

Thats a serious misfire that can damage your cats...I think its called a type A misfire. Gotta get that fixed.

Yup, it means you're dumping fuel down the exhaust which overworks the cats and will cause them to fail early. Don't drive it like that. I'd go coil next.

I finally got the new coil and wires on today, wadda ya know? good as new. however few hours later ses back on, this time it's the F*****g cat converter just like I was warned about. How long can it be driven like
this? It still runs great.

what code did you get now.. you might not have fried the cat, clear the code reset the KAM and see if it comes back..

NEVER NEVER NEVER drive a car with a misfire.. if that check engine light is flashing tow it home.. now you know if you have this happen again to another car..

I don't remember the exact code, but it was something along the lines of Catalyst Below Threshold. And this is a NEW code because I cleared the misfire on # 6 code before I changed the coil and plug wires. And I know I should not have been driving it like this but we had no choice. My other car's water pump just went kaput, now I'm trying to sell it.

Unless you drove for a while with the problem, it's probably a coincidence that the SES light is now on signaling a possible problem with the cats.

Probably not a problem with the cats, but with the O2 sensors that are used to monitor the preformance of the cats. With time and miles the O2 sensors become inaccurate, triggering the SES light for cats.

No, the catalytic sensors are rarely wrong. Still it could clear up. Keep an eye on fuel economy.

^^^^^^^ +1

99% of the time a P0420/0430 are due to cat failure. Could be that that cat was almost about to set a code, and driving it with the missfire pushed it over the edge.

Clear the code and drive it, but if it comes back on with the same code, then you're gonna need a cat.
