I found a website that sells them for $60's and up (link below) now installing it could mostlikely run you a minimum of $100 I thinking no more than $200
It would be mounted in the exhaust pipe downstream of the catalytic convertor Helpfull
Your best bet would be to take loose the catalytic convertor and see if it is stopped up. you can run it like that for a few mins. to see if that is what is causing the problem. it might kick on a trouble code. I had a car do that ran fine then when it warmed up a little wouldn't go over 20mph. pulled catalytic convertor off and it ran fine. If that is the problem you can replace it with a generic catalytic convertor not one from the dealer to save some money.
That would be the sensor after the catalytic convertor.
Bad port on the spyder injector , or 0xygen sensor going bad , and pluging up catalytic convertor
YES ! as soon as the engine was started , you would notice how noisy it was The catalytic converter(s) are in the exhaust system before the muffler , and removing the catalytic convertor just leaves an open exhaust pipe - extremely loud
You would get crappy gas mileage and you would hear the engine humming real loudly. It's not a good sign, by the way.
My guess would be a plugged catalytic convertor. If the tailpipe stays cold, that pretty much confirms it. Let me know if that helps.
An exhaust restiction, like a clogged catalytic convertor
could be a zillion reasons why, but check for a clogged catalytic convertor. Good luck
Usually each side or bank has a sensor that monitors o2 in exhaust and adjusts run time on injectors, sensor 2 is usually behind convertor and may be shared by both sides, it monitors efficiency of catalytic convertor. I would replace sensor first since they are cheap and appears you have no problem with the ones controlling mixture. Only running excessively rich (raw fuel) will prematurely kill a convertor and under normal conditions they never wear out. Look more closely at that after you have ruled out sensor.
A generator belt on a 2003 Volkswagen Jetta costs approximately fifteen dollars to replace for the part only. Labor pricing would increase the total cost.
