Starts but dies right away

I had the same problem. My cat. converter went which plugged my muffler and choked out the car seconds after starting it. I took the exhaust system apart between the manifold and and cat. (3 bolts behind the motor by the firewall) then started the car and ran fine. I now need a new cat. and muffler for my 2.2 Alero.

How many catalytic converters on a Mazda Mpv 2003 van?

I disagree. I believe there is 2 cats on the 03 MPV. If you look under the car. The 2 pipes from the headers meet right before the muffler. There is 1 cat under the vehicle and another right off the header (looks like an old glass pack muffler).

Showing code cat? we changed all coils it runs great now!

It's part of the exhaust and for emissions, looks like a muffler only smaller. Need to go to a muffler shop to have it replaced, or repair shop.

Catalytic Converters

You are correct. That portion of exhaust is indeed a catalytic convertor. This would be in the rear portion of the pipe with a flexible section that goes underneath the oil pan. Then you have a long muffler and a final muffler in the rear of the vehicle.

Careful. this sounds very high and there are generic cats that any competent (and HONEST) muffler shop can install with a Mazda or generic muffler.
Don't know how labor is in your area but the cat and an adequate muffler together shouldn't cost over ~$200 US. Check with a 'parts' store that doesn't do installation to see what the individual pieces cost 'over the counter.' If you are in the US, check with your local Better Business Bureau website to find an honest shop.
