So a miss from a single, slightly flattened cam lobe will often start to go away as engine rpm rises and the lifter pumps up, but will probably reappear at very high rpm as the cylinder begins to once again starve for airflow. Engines with solid lifters may or may not experience low-rpm or idle problems.

What can cause a cam / crank correlation problem?

Variable valve timing (VVT) system components can cause cam/crank correlation problems as well. These systems are often dependent on oil pressure, so checking the oil level is a good place to start. A plugged or failed oil control valve can also cause VVT problems.
