I started to get a misfire about a week ago so I went ahead and changed plugs oil and regular maintinance work on it. Now the car runs worse, I get a misfire when the engine has a load on it. While its idleling its fine but when i drive it misfires and now i have a P0307 code telling me a misfire on #7. Side note I have a build up of a yellow/off white substance on the driver side head and when i took off the coil on plug it was milky yellow/off white crap in the upper spark plug...

move the COP to another cylinder, clear the code, and see if it follows, if so that COP is bad.
