I'm leaning toward a VVT issue as well. I'm told that the cam timing is advanced at low rpms and retards as rpms increase. A rapid acceleration may result in a "lag" in the cam timing, resulting in an erratic signal from the cam positioning sensor. Why only cyl # 7 is affected, i'm not sure.



I would think this is not the case as it only is affecting one cylinder. If it was something like the VVT it would affect other cylinders as well.

Now having said that this engine is an MDS engine correct? I don't know what cylinders the MDS kills but there are four separate solenoids in the valley that control it, there could be a solenoid or harness problem if #7 is indeed one of the cylinders it kills.
