I heard a few members talking about this issue at Carlisle and Heibeck said to check the 02 sensors.

I swapped out my ignition wires today it seems to have solved the problem...I got car warm ( was 76 today in NY) and got no hesitation...

Maybe too early to tell but so far the wires seemed to help...
