Wondering if any of you R guys can help me out. Here's my original post: https://forums.swedespeed.com/showth...ck-engine-woes
basically, I am trying to clear P0134 code I get with the catless revolv downpipe. I bought a O2 spacer kit but can not get a configuration where I do not get a check engine light containing the code P0134 or P0132.
Currently using a straight spacer paired with a plug non fouler but am still getting a p0132 code.
no codes before dp upgrade.
