I just picked up this 97 V6. Anyways it has an intermittent miss at idle. I figured it just might need a tune up, it did, the electrodes on the spark plugs were burnt off. So I put new Motorcraft plugs and wires on, I gapped the plugs to .054 which is what they told me at the auto part store. It still has that intermittent miss. Could the coil pack cause that? This is the first car I've owned that has had a coil pack so I haven't really ever ran into a problem like this before. What do you guys think?
