I have a 2001 ford ranger. I just recently purchased it, and I thought I'd do a tune up on it so I did. I put new wires&plugs and now when I drive in town my check engine light comes on, it shows code p306, to which I know to be a #6 cylinder mis-fire, I've chanded the plug&wire 2times now& I still get the same code. If I clear the code& drive it on the high-way the light never comes on, but in town it will. The size of my motor is a 3.0L, do you have any idea what it might be?
