Hello all. I was driving last week i my '12 Eco MT with 151K miles . It was pouring down rain and I had been driving about 20 mutes on the highway the car was at temperature. I started to go up a hill and the car stated bucking. On the next hill it started gain and the traction control light came on and the CEL flashed but didn't stay on. After the 2nd hill, anytime I would put the engine under load it would hesitate and almost stall out. I stopped the car when I got where I as going and stayed for about 2 hours. When I left it didn't start up again until he car got up to temp. This time the light came on and stayed on. I drove it the next day and had 0 issues. After a few cycles the CEL went out. Occasionally now it will miss when accelerating, but no CEL. I used Orielly's scanner and it said random misfire and #3 misfire. I am thinking it's time for a coil? Any other ideas? I am all stock except the airbox mod...and that shifter handle that adds 200h.p.... Plugs are at .028, about 15K on them.
