running rough. Fails contribution test for #8 cylinder, but compression is good and injectors are good. Had it looked at by a diesel shop, but their expertise is more with fleet/commercial trucks. Can’t afford to throw money at something until it sticks. Ford already performed the recall swap of the cam sensor. My next thought would be a boost leak test when it is warmer. No garage. Runs like a gasser with a timing miss, and you can smell the diesel at idle. 310,xxx miles, stock.
