I recently had the gas tank fixed (had a hole) and now the check engine light has been on. IDK if they are related but Im trying to figure out where I should start to fix it. I dont even remember if it was on when I took it in for repairs. It had sat for like 7 months because it needed new rack and pinion (which the same guy also replaced) The car seems to run fine. The mechanic didnt even notice the light which makes me annoyed. I been reading different posts and cant solidly figure out if my car actually has a code that can be read?
