Well it has been over a week since I took manny's advice and cleaned my MAS. Since then I have had no issues with hesitation or surging. My POWER is back, car runs great - Life is good!

For the many issues that can be classified in the hesitation category, this fix might be often missed (especially since the MAS was brand new and acted up just days after I installed it). But this was just one answer as plugs, wires, coils, fuel filter, rev limiter... and the list goes on, are all "fixes".

I will admit though, I learned a ton about my car by running searches and checking out the oodles of threads. I'll tell you, there are answers out there if you are willing to take the time to read through them.
Thanks everyone!
