@robzues09, This is my situation exactly. @BMW3-SERIES, that video is exactly my problem. Did either of your cars throw codes? No codes here.

They will tell you these symptoms are also consistent with fuel starvation -- like a clogged filter or a weak pump. But in my case, fuel pressure at the rail is good (53psi), and I have already replaced the pump and filter. Today I am going to drain the gas tank, because I have no way of knowing how old the gas is. Robzues09, was your car sitting for a long time? Can you check your fuel pressure? (A gauge is fairly cheap at Autozone.)

I have changed out my crankshaft position sensor, but not my cam position sensors. No codes. I'm going to try new fuel then shell out 200+ for new CPSs, but at that point, I'm just throwing parts at it. Might as well try a new MAF and upstream o2 sensors, too
