Do not destroy the evidence prior to and during the investigation.
Have you had the intake manifold vacuum checked with the engine running at idle both cold start and at normal operating temperature?
What was the fuel trim reading from the scan tool?

Can you post a screenshot of the engine data from the scan tool? 9 out of 10 the problem can be determined from what the PCM has on its freeze frame data.
