[QUOTE="lps83, post: 458241, member: 24564"] I saw the previous video. It's a ground problem - apparently common on this car. The engine warms quickly; I believe my thermostat is properly working. I realized that the catalytic on <2009 models are different. The sensors are way closer to the headers. Since I changed my ECU, that may be the reason. The sensors are correctly heating, but because they are further down in the piping, they don't heat that fast, and that triggers an error code. [/QUOTE]
