The cat on my 97 jeep wrangler has been removed for a while. The check engine came on so I ran a diagnostics on it, came up as both up and downstream 02 sensors, I replaced the upstream and it still runs funny. The diagnostics after I replaced the upstream said its the downstream but because I dont have a cat their is no downstream
have the same problem?
