I mean a flat spot, miss, stall, hesitation almost die out.I dont think it is anything like a ping from using lower octane gas, or bad timing etc.

It can vary from almost a hiccup , to feeling like the engine stopped completely for one second or more, if I do not back off on the pedal . It varies according to how aggressive I am on the throttle.

More gas when it happens, it almost dies totally. Less gas it hesitates/sputters for a shorter period of time. I think I just instinctively back off on the throttle when I feel it , so as not to cause any damage.

Feather the throttle and no problem whatsoever. I have become very proficient at feathering, and could probably drive witout breaking an egg on the gas pedal.

The few times I tried to power thru it by giving it more gas, the engine just felt worse and nearly died completely on me.
