[QUOTE="Catmonkey, post: 16527397, member: 124025"] Normal cylinder compression on the 5.4 is ~150 psi. Unless you're running cams, I don't see the 5.8 being that far off that mark. You may want to get a bore scope and take a look at the cylinders and tops of the pistons. If you think dry cylinders have something to do with your readings, repeat the process on a warmed up engine. As a side note, the PCM is pretty effective at ratting out misfires and the ability to do so by cylinder. [/QUOTE]
