On my way home from work i was driving and all of the sudden the car started shaking real bad and cel started flashing at me. i pulled over and checked my aeroforce gauge and it gave me the following codes: P0171, P0202, P0300. The p0171 i get randomly which is more than likely a vac leak some where i cant find. The p0202 is cylinder 2 circuit malfuntion which im guessing is causing the misfire code. any one else have this code? any ideas if it could be the injector or connector?? Help quickly would be greatly appriciated!!
