today i was driving went to change lanes and it just started flashing the check engine light at me. if I am going at easy highway speeds everything is fine. if I have to cut the wheel at slow speeds or attempt to climb a hill it sputters really bad and kicks. sometimes just easy driving does this also but if I let off the gas and ease back into it levels out. I had the code read and of course it is the generic p0300 code.
I had replaced wires and coils about 3 or 4 months ago but the plugs looked fine so I let them alone. any ideas?
