Thanks for the feedback guys....
MarkWB---Fuel pressure regulator, not a bad thought at all. Gonna have to check that one.
Billboost37---I replaced the wires and plugs after the car came back from dealer. Ran wires exactly as factory wires were run, and have just double checked, not laying on O2 sensor. Another good idea though!
TechnicalTed---The code showed for the dealer during their code scan but nothing showed for me on the DIC(driver information center).
This is a pretty intermittent problem and does not happen all of the time,but, has been becoming more frequent now. I watched yesterday as I was driving noticed that the Tach does not fluctuate with the hesitations. That kinda makes me think...look at transmision,motor mounts, driveline and not engine. Does that sound reasonable or am I all wet????
What size is that blasted supercharger oil fill plug?
