engine light???
hey everyone,
i have an 08 HHR SS wit alittle over 14,000 miles on her. its all stock except a K&N filter on it. As far as i know it doesnt have a stage 1. (i bought it used). well the engine light comes on when im on the highway at speed, 65+. When i reset the computer it runs fine untill i get on the highway. OK now.. today the light came on again. Went to get the code scanned... It said "P2178 System too rich off idle speed (bank 1)"
Can anyone tell me what i can do to fix that? Is the K&N messing it up? Do i have to get a tuner to run a K&n filter and is it worth it? What tuner should i get?
