Hi guys!

Developed a misfire, sanned codes came up with:

P304, cyl # 4 misfire
P300, random misfire
P304, cyl # 4 misfire

I changed the spark plugs and spark plug connectors.

Cleared the codes and the MIL atcivated again.

Code read:
P304, cyl 4 misfire.

My question is: I've had bad coils before and I have yet to see a coil FAIL and it affect only ONE cylinder. Could I possibly still have a bad coil????

Any ideas would be greatly appreciated as I am kinda lost on this one!

Thanks in advance, guys!
