I need to replace the muffler on this 95 blazer I've been working on and while I was under it looking around, I noticed there is no O2 sensor around it, just a capped off plug. It being a CPI system, can I just take it out? It runs too good to be clogged, but just wondering if I'm the only one that's thought about this or has anyone actually done this and does it, or will it, affect the computer? Not that I would break the LAW, just wondering!
