So I pulled this error for my 08 Lancer ES. I have been doing alot of searching and it seems this is connected to aftermarket intake installs. However there are no engine modifications done to my Lancer. I brought it to Mitsubishi and becuase I am over 60k they are telling me more then likely the problem is not covered. So my question is where should I start. I have a four day weekend to work this bug out so any help would be great. Thanks
