Chosen Solution
Dead cylinder 4 unsure why. Rough idle running, zero compression in one cylinder and low in the rest (8 bar)
@hamzamsj this “zero compression in one cylinder and low in the rest (8 bar)” needs some serious work. You do need theck your valvetrain and your Pistons, head gasket etc. as well as multipole other things. Do a leak-down test and see what that reveals. A compression of zero will cause all the other symptoms you are referring to. Anyhow, I am certain a manual will be available but you need to let us know what exact year and engine size your VXR is.
