I've got an 02 Lightning I brought to the local Ford dealership with what I thought was a bad coil. After 1 then 2 techs looked at it and a foreman who came and looked at it after 2 weeks at their garage, I'm told I need a long block. Compression loss in cylinders 1, 2, and 5. I take it elsewhere and relieved to learn it was only a cam sensor and a disconnected injector. The cam did jump a tooth. Replaced the sensor, Compression just fine, and she runs like the day I bought her 20 years ago. To think I was looking around to do a rebuild and needless costs!
