So i know i need a tune up and i plan on getting it done this weekend while i continue my busy schedule (i just don't have the time to learn myself right now), but betsie threw some code at me as i have just recently ripped out my carpet. Randomly my check engine light would come on but after i turned off the car and cut it back on, it would disapper for a few minutes or weeks and then return. Well it has been a bout 2 months since the last time, but now it has done it again and i am looking at the code (i get 12 continuous flashes, and a pause and then 12 continuous flashes again). well this website tells me what the flashes mean but is it applicable to my car cause iono what an ERG is... http://www.crxguru.com/tech_notes/ecu_codes_page2.htm . could someone tell me if this is serious and or how to fix it myself if possible. Oh and i just got my HAN shirt...it is sweet.
