The car was spitting d sputter and overheating on the main hightway. . . Engine light started flashing a d it showed misfires on cylinders 2,4,6. . . . The problem is on going and has had my 2 year old and myself sitting on the side of the road in 110 degree heat index waiting on a tow truck!. We were driving straight down the main highway. Then the accelerator would be floored but the vehicle wouldnt move at all. Thus I couldnt cross the last main highway to get home.
