I got this 05 wrx, and naturally i like going really fast sometimes, well yesterday on my way to work i was doin 120 in a tunnel and the check engine light suddenly came on. i did the diagnosis, and it said "Manufacturer contrl ignition system or misfire". i went back into advanced auto parts and asked if they knew what it was and they told me to ask the dealership i bought the car from whens the last time they did a tune up(bought the car recently). im not sure what that manufacturer contrl ignition system or misfire means, can anyone help? i must say the dealership i bought it from was really cheap so i wouldnt be surprised if they didnt take well care of it.
