i think its a misfire, but i also got a notification P:0303 and another 2 like it. Could it be a bad coil or a plug?

 

anyone?

 

I had the same thing just happen to me. I changed out the plugs with NGK 6994 Iridium Plug's and everything is back to normal.


Clear the trouble codes and try changing the plugs first before you start with changing out the coils. Good Luck!

That sounds like a good step. So far I don't have a problem with the engine at all. But if I had ragged firing or misfiring I would do that.
