Just to close the loop.
1) I had calledthe dealer regarding whether or not to use additive. He suggested to add the HEET ( water removal additive ) to the gas as he strongly felt it was bad gas causing the problem. so . . .
2) I added the the HEET
3) Then drove around on the freeway to get a good mixing in the tank
4) The hesitation / knocking actually got much worse before it got better. Apparently took awhile before all the moisture was removed from the tank.
4a) As I was driving about, I left the OBDC II scanner connected to monitor the progress. It turns out I logged several more misfires ranging from P0300 , P0301, P0303, P0304, P0380. The P030x (x = 1, 3, 4) refers to misfires in the corresponding cylinder. P0300 refers to randomn misfires. P0380 refers to high voltage on O2 sensor. All of these errors were expected since I was burning trash gas.
5) Bottom line . . . It took one bottle of HEET and some scenic driving around (30 minutes at various speeds) to remove the water from the gas. So now I'm back in business.
Thanks alot for all the help - didn't get the chance to contact danman32 - I'll save the info for my next problem.
