i'm hoping you guys can steer me in the right direction
my car has had a miss for about a week now, took it to my mechanic and his scan said that clinder 3 was miss firing 300 times and cylinder four had about 4000
miss fires.

the funny thing is the car is not throwing any codes and i only few the stumble or hesitation when i start out from a dead stop, then she feels fine.

what on earth could this be?
thanks
