Check Engine codes help!!!
Keep getting codes P0300 Random misfire and P0171 system too lean bank 1. The car shakes (with a really strong gasoline odor) only at idling and/or chokes when starting on 1st gear from a stop, no issues under acceleration, down shifting, etc, the car feels responsive otherwise. So far I've put new plugs and wires, cleaned the MAF sensor, air filter, throttle body and checked for vacuum leaks. Mods are Vararam CAI, LT headers, Diablo tune, all done approx 3 years ago without any issues afterwards. Suggestions are appreciated. Vette is a 2005 with 89k miles on the clock btw. Thank you!!!
