I'm interested in hearing the engine to determine if all 8 cylinders are firing.

Did you verify that each HI-TENSION lead is providing a signal to its matching plug?
For example, if one coil is failing, 2 cylinders will go off-line.

Did you verify that each primary injector is getting a (-) signal from the ECM? One failing or partially failing injector or (-) signal to an injector will be very noticeable at low RPMs.
