Random misfire

[12sonicltz]

I just replaced the plugs and ignition coil. It seems to be running normal, but I gassed on it and it misfired. I got a cylinder 3 misfire and random misfire code. It drove normal after that. Any idea what would cause this?

Check your gaps make sure all your plugs are tight check your coil make sure there is no corrosion check the coil wire make sure its connected good
