Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral until radiator fan comes on. Allow engine to idle. Using scan tool, check manifold absolute pressure. If indicated pressure is 12.8 in. Hg or less, problem is intermittent. System is okay at this time. If indicated pressure is more than specification, replace MAP sensor.
