Well, I'm an idiot. I figured I would be able to pull a fast one on the new OBD I/M emissions testing that was just implemented here in my county. To make a long story short, I failed because of four "not ready's". The car: 2003 WRX, UTEC, Stage 3. Three cat related ones (because of my resistor fix for the rear o2 sensor) and one Evap related (because of the UTEC). I fixed the Evap related one yesterday but I guess it takes many drive cycles for it to show a "ready" status. After failing today, I took off the resistor fix for the rear o2 sensor and switched over to a mechanical fix using the HELP! 42009 parts. From searching around, I guess I'm gonna have to do 30 or so drive cycles before all of the sensors show "ready". Luckily I get a free retest. What was the lesson I learned? Don't fix something today hoping to pass emissions tomorrow. Hopefully my experience will help someone else to better prepare for an emissions test in the future.
