Ok but are you referring to the MAP sensor or the Mass Air flow sensor?

When I have P0420 it was a bad cat. I changed it right meow and all was good. :)

What problems was your car giving you when you found out it was the cat?

The PO of the car had a very small cat on it, and a burnt out CEL bulb.

Here is some more info..... http://chrisb.users.superford.org/Gr...Converter.html

ok thanks

I am considering having my cat removed permanently. Do you think the check engine light would continue to stay on after I cut it out and replace with a straight pipe
?

The other code could be one of a few things, Could be a bad rear o2, could be a bad front o2, could be a bad cat, could be a aftermarket cat not doing enough as far as your engine computer is concerned. Personally? I would replace the front o2 if it is more then 60k miles or 5 years old and then do the non fouler trick on the rear o2. You don't need a o2 sensor to tell you when your cat is going bad. Trust me you will know because your car will not go over X mph. Also ignore all of that cleaning bull****.

I replaced the MAP sensor and still the same problem exists. I am pretty sure its the CAT now. Whenever I throttle very hard trying to pass someone the car stalls outand looses power until I let up off the throttle again.
