You need to get the ECU scanned for trouble codes. That's a free service at many of the national auto parts store's.


bullshit. anyone knows right away its your air filter is overly dirty. i promise you. change your air filter and then after you change it. unhook your battery for 30 minutes then hook it back up and you will see.
