Message my results are uneven by a decent margin when comparing the driver side to the passenger side, with the passenger side being higher. All results are DRY
5. 160 6. 145
3. 160 4. 140*
1. 155 2. 140

*got a much lower reading at one point on this cylinder 125 when the engine was warm. had gotten 140 previously and 140 again about 2hrs later when engine had cooled. Don't really know why I would get a higher reading when cold.

I know difference between the cylinders should be no more than 14 psi, I'm more than that. Can someone please explain these findings.
