My check engine light came on and autozone said that it was a catalytic convertor problem. I looked and no one sells a new catalytic convertor except nissan dealers. I looked at the jerry-rome site and they were 800 bucks. I looked on ebay and they have the (illegal?) high flow pipes for only 30 dollars.

Any advice on what I should do????

 

You won't pass emmissions with a straight pipe (I would guess NY has emmissions right?).

 

Salvage yard! If you don't know of any local ones, try car-parts.com.

 

You can get cheap (in price and quality) catalytic converters from Midas etc... depends how much you care about the part quality.

 

no emmisons in NY

 

Most aftermarket cat converters are bad quality. The OEM cat costs around $800 but the honey comb "filter" element in there is superior to those sold in the aftermarket cats. If it was a cat problem maybe the O2 sensor is the culprit. If the cat is bad, it's most likely due to your car running rich and making the cat go bad. Get a new one and most likely it will go bad too and a lot faster than the stock one. Maybe 2 weeks time?

 

How about this:

I never actually bought one from them though I was thinking about it.

 

Someone else sells them you just have to find it. The link above works, also check out a good junkyard.

I don't think a malfunctioning cat would trigger the Chk.Eng. light because that's strictly a mechanical device. The O2 sensors are electronic and could trigger the light, but I thought they're sitting prior to the cat, so they "wouldn't know" if anything was wrong with the cat....
In any case there is something wrong with fuel supply/ignition/emission systems that triggered the light...

 

Don't 99s have four sensors; one in each part of the Y, one precat and one postcat? Read your ECU codes.
