Premium Fuel Lag

Premium Fuel Lag
Hey guys.
Scenario.
I've been using premium (91) and regular(87) fuel off and on.
But I've noticed something.
I've noticed a slight lag, er hesitiation, or whatever when I'm using 91.
The rpm kinda drops a few hundred rotation at around 3500 and then continues rising again.
Is anybody else having similar problems?
Why is this happening only when I'm using 91?
I've waited for the ecu to adjust... about 600 city miles...
???

Yeah, I'm sure.
I had the problem before so I switched to 87's
But then I read all the threads about knock sensors going bad, so I switched over to 91's again.
The the problem started again.
I'll reset my ecu today...
Just to be sure...

2.Ignition
3.Counterclockwise
4.Ignition Off
5.Clockwise
Right??

Turn the car to "on", turn the screw all the way to the right for 2 sec, then back to original position. Read any codes, and to reset just turn it to the right again for 2 sec and back again. Then turn the car off. Better yet, check the stickty at the top of the forums
