I have a 2002 Honda accord. Ive only had it for a few months. I haven’t had any real issues with it. The other day I left for work and stopped for gas. No problem. As soon as I start the car back up, its thumping and my engine light is blinking. Quick Google search tells me its dangerous so I ran to advance auto to get a printout of the codes on my way back home. Turns out I had SEVEN codes. Misfire in cylinders 1, 2, 3, 5, and 6. A mechanic friend of mine walked me through checking my ignition coils. With the engine running, I unplugged one at a time and listened for a change. Nothing happened when I unplugged them, except for one. So FIVE of them went bad? At exactly the same time? And beyond that… I’m at a loss for how this car was still drivable with only one good coil. Didnt even sound bad. The thumping was even minimal.
Ive ordered new ignition coils to replace all 6, but I’m completely at a loss as to how or why they all failed suddenly after getting gas.
