Unless its the MAF sensor that is bad and causing this than other than that I have no idea. I've had the car ohh maybe 6 or so months now and have done the following to it all my self too, I love the car its a great car except I cant figure that check engine light to save a life. I am confused, and I think that's what's causing my check engine light to be on. It only did that the first time and after that it just would never have any effect, plugged on or off car was still running fine. First time I turned the car on, he unplugged my maf sensor nothing happened than he plugged it right back in and it shut the car off. my brother has the same car and when he unplugs his his car shuts off but mine stays on. I am trying to figure out if my maf sensor is bad or not.
