I have not checked fuel pressure but I will have to. I do not have any check engine light at all so I’m trying to investigate further. I would hope that the fuel pressure is good as the fuel pump is only 6 months old. I would agree with a possible pcv problem because of the excess oil residue coming out of the valve cover so I’ll have to start there. I haven’t had any shop look at it yet as I’m pretty handy when it comes to working on it. I’ve done new plugs and wires, oil change, cleaned out throttle body and mass airflow sensor. But no fix in the problem. I’ll have to start by pulling the valve covers and check it out. Thanks</p></blockquote><p></p>
