| You don't say say which IO you have. Anyway. The pressure of the high injection pump seems to be correct. You must make sure that the ETV is operating smoothly. Sometimes there is fuel leaking from the pump and mixes with oil, the vapours from this are sucked into the engine the number 4 and 3 cylinders are running very rich. The sparking plugs colour ( always black) is not a good indication of the A/F strength since in this engine the mixture strength in the vicinity of the sparking plus is always rich. |
