So the CEL came on during regular slow *** driving and my idle shot to 2k. I don't have a cobb AP or anything to pull codes. Car has 21,000kms on it and It's an 08 gsr. Got the car less than a month ago from a mitsu dealership.

I have searched here and haven't found the right information to approach the dealer with.

Anyone have any suggestions?

Edit. Car is stock.

 

Go get a code reader from Autozone or a place like that. They'll let you borrow it. Pull the code and post back up on here. That will be the best start.

 

Problem fixed itself. Guess my electronic boost controller spiked a but too much in last nights cold weather.

Thanks
