I've been getting an intermittent check engine light for the last 6 months with my 2002 Ranger XLT 3.0L (130,000 miles). The OBD analyzer indicates a miss in cylinder number 4 but, if so, I never notice it. The check engine light stays on for a week or so and then goes off.
I have replaced the spark plugs, plug wires (with Motorcraft set), and cam synchronizer (Motorcraft) all in the last 3 years and 10,000 miles. I have not touched the fuel injectors other than to try a can of Seafoam.
I pulled the number 4 cylinder spark plug but it looks clean and properly gapped.
The check engine light came on more often over the winter but has become more frequent of late. Any idea as to what causes this?
