    I've noticed a very annoying thing lately. When I'm driving on the highway in 5th gear (MT) and apply full throttle I can feel the power increase from the VVL, but I notice that sometimes it pulses and doesn't want to apply smoothly. This causes a slight power surging and if I slowly let off the gas I feel a point that actually accelerates better with less throttle. Could this be a bad VVL solenoid, or something with the fuel mixture? Im at a loss. It seems like bad engineering to use two separate oil pressure sensors for the VVL system since oil pressures could be different on the two sides of the engine, so the VVL system doesn't engage at the same time.
