I am getting P0420 which is insufficient catalyst. I'm told this could
be a bad O2 sensor (inexpensive repair) or bad catalytic converter.
Funny thing is, the engine runs great; 25 mpg. I'm hoping it's a
bad O2 sensor
You might want to check with the dealer to see if a PCM flash update is
for that car. There was one for certain CVs for exactly that problem. I think
loosened the parameters on the cat monitor.
I would check with the dealer but I don't trust them. They will not
benifit by a simple fix. Forgive my sinicism (sp?) butI have been
taking a real beating lately on this car.
I will have another mechanic look at it.
Thanks for your info;

You car most likely has a bad cat. (this car had running probs for quite
a while right?) If it is the cat you should be able to have a local
muffler shop replace it for about $150. It won't hurt to drive it in the
mean time....also, Tom knows Fords- I would listen to him. If you had a
bad experiance at a dealer, go to another one (lincoln or ford). Tom,
wouldn't that update be free, like a recall of sorts? You could call the
dealer with your VIN # and ask them if it needs an update flash.
Thanks for the kind words ShoeSalesman, I'm blushin'.
It's possible that the cat has failed due to the previous misfiring. If
I think the reflash would be free of charge because it's emissions related.
could be mileage parameters though. If it applies it needs to be done though.
the cat is bad, the more rigid parameters could cause the code to set. This was
reason for the reflash.
you're blushin? lol You're supposed to say "ahhh shucks". :) I've delt
with a lincoln dealer quite a bit and it seams there are updated flashes
that come out as a recall. Could he not just call a service writer with
his VIN# and find out for sure? Or better yet cruise in there and ask
them without leaving the car.
That's why I asked. I remember the phrase, but not quite the character. It was
white dog that played a character called Deputy Dawg in some cartoons. I know
Deputy (Deppity?) Dog character, but who was the white and black dog that had
alter ego. The DD character was a part of the show. I remember another character
called Tennessee...something....? He was blue\purple...? They all resembled Yogi
being IIRC Hannah/Barbera toons. It sure sux when you can't remember things from
recent times like the 60s. ;)
