I have a code come up over the weekend. P0301 bank one misfire. I drove to the nearest autozone they checked it out and gave me that. But when i turned off my car and started it the code and the misfire was gone????????? WTF?!?!?!?!?!? what should i do change the plug still or the coil???

 

Your coil is probably going. Call Dave B and get a new one.
