I have changed all the spark plugs. The check engine wasn't on anymore. While driving I could still feel a misfire. I knew I wasn't delusional and sure enough the light came on again. I could feel some hesitation when I hit the accelerator. I check it with the OBD and got the code P0316.
-
Unfortunately there are many things that could trigger the engine misfire, which is what triggers the P0316 code. I suggest start with the more simple stuff. Try using another gas station, or use high octane gas for a couple of weeks and if possible change the air filter and add a fuel additive.
