After driving for about 20 miles on the freeway, the check engine light on my 2010 Honda Accord started flashing. When I stopped the car, I felt the car shake and rumble, but it operated fine while driving. I looked up the symbol in the manual, and it says something might be wrong with the emissions Is this possibly it? Should I take my car to the local mechanic I use or to Honda? What do you think might be wrong and what are the possible costs to fix it?

Answer

There are a few possibilities for this scenario. It could be a fouled spark plug, inoperative coil, faulty fuel injector, piston rings, etc. The check engine light is flashing because there is a misfire and it could be causing damage to the catalytic converter. I recommend having the Honda dealer check the code and give you an estimate of the cost of the repair.
