ive searched and havent really gotten a solid response about this issue or maybe i didnt search well enough.

I just got the 136 and 141 code i know what they are but can i order a o2 sensor for the midpipe from anyother place or does it have to be from mitsu? Really dont want to spend the 250 for a o2 sensor, do the universal ones work and where can i get them from? thanks

 

Try mistubishiparts.com's oem catalog or give summit racing a call

 

you may try one of those 02 sensor anti-fouler setup.

simplest way to go is weld a 2 to 3 inch length pipe with a thread to fit the 02 sensor to the existing location, so it'll get heat up without telling the ecu that you don't have a cat.

maybe that will help.
