Clean the old map and check the cable first before buying a new one. There's guide on safe cleaning but dirt or dead bug stuck on the map can throw bad map. Check the intake air filter if it was dirty map.

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

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

P0420_001.JPG



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/Grand_Prix/Projects/Catalytic_Converter/Catalytic_Converter.html
 
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
?

Sounds like you need a map sensor, Costs about 40$ from amazon and is a 5 min job to replace. 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.

Ok forgive my ignorance but what does getting it tuned out mean exactly.

Having someone with turning software have the code set not to report. So your SES light wont come on for whatever code for the car.

Edit: oops didnt mean to double post just edit my first one lol
