I went to my local Subaru dealership today and bought an air filter. I installed it when I got to my business and didn't think about it till I left later tonight. The check engine light was solid and the cruise control was blinking. So I checked everything to make sure nothing is unplugged and that the filter case is closed tight. No problems there. The manual for the car is useless for stuff you need so I was hoping someone here knew why my car started doing this and how do I get it to stop without going to the Subaru dealership. I don't want to have to pay the dealer to do stupid installs like an air filter just to avoid errors in the dash. That seems like a scam to me.
Also, I read somewhere else online that when it does this it puts the car in "limp mode"? Allegedly 30% less power, is that true?
