I had my cps pigtail connector pins get spread out due to not re installing the clamps for the harness along the front cover. Took me a while to get it figured out. My truck had a violent hiccup, seemed like a miss at higher rpm's. Sometimes wouldn't even start. Pushed the pin connectors back together, and have not had an issue since.
I did take the pigtail out and look at it. Nothing really jumped out at me. I didn’t notice any misses when I drove it this evening. I should have another CPS somewhere. They are from Ford.
