no it's just epa crap, I have my tech2 i'll have to hook it up and see what it says is going on, I also need to probably replace a hvac sensor and probably a blend door actuator that was going funky in the summer but it didn't matter then because it was always hot now it blows cold in the back unless I hit the rear ac control even if it was already preset to 80degI have the same intermittent message...other than the annoying message and check engine light that comes and goes, any immediate harm?
