I'm throwing the 2-3-2 code, and have been for about the last week now. I keep resetting it, as I haven't had the time to more deeply look into the problem and I hate seeing that check engine light on. Here is my question for you all. Has anyone dealt with this problem before? I inspected the vacuum lines and found one with a slight leak, but I replaced it last night, only to get the code again this morning. I have thermal wrapped the downpipe (stock), so is it possible that I'm overheating the O2? The only other thing I've changed is I replaced the factory air filter with a K&N unit, but I seriously doubt that has done anything. Thanks for your help!
