Denny,

What bothers me is that it runs perfect with tlots of power when the outside temp is cold. Keep in mind that it ran perfectly when the outside air temperature was below 50f last Monday. This would not be a charcteristic of plugs, wires, cap/rotor etc. I did 65mph for an hour and a half and it only started near the end of my trip when the outside temp rose to about 51 (I have an outside temp readout on my electronic compass) When it starts its thing is perfectly predictable looking at the temp guage as long as it is over 50f. I will be getting the Air intake and coolant sensore later this morning and will let you know the results. I realy appreciate your input (that goes for everyone else also). I see by your website that we are the same age!
