I recently came into possession a 2002 Ranger with a 3.0 V6 with 136xxx miles on the odometer. When I got it, it had a rough idle and the Check Engine Light was on. My OBD showed it as a P0301 code. I put in new plugs and wires (I am pretty sure they were original) and the engine now runs very smooth. I have never owned a Ranger before but it seems to run fairly strong. The problem is that the P0301 code keeps coming back. I can clear it, but it will come back after a day or so. I did a compression test and all the cylinders were between 125 to 150. #1 specifically had 150 on the compression test.
With that compression numbers should I even bother with a leakdown test? Where do I go from here to figure out this gremlin?
