whats up guys, so iv had my jeep since about august, got it inspected went through that whole deal and i get a test run on my jeep to make sure everything is good. they tell me my rear cat converter isnt 100% but say that its not a problem but just to keep an eye on it. ever since my check engine light has been on because of it. it recently went off the other day, and has been off ever since. im wondering what kind of problems i could run into if i dont get it fixed or if it will take away horse power or anything! Help me out!
