    P0307 , cylinder 7 misfire code

    I had a rough idle today and threw this CEL code. I'm going to start with replacing the spark plugs. Just wanted to see if anyone else has sugestions beyond on in addition to this. Also I'm going to research which spark plugs to put in but sugestions are welcome. Thanks so much.
