Does it change if you turn on and turn off your A/C? I ask this because if the A/C compressor is old and working really hard, I have seen it cause rough running with out setting a Check Engine Light, other wise, if it is a power train management issue, a Service Engine Soon Light will almost always illuminate.

What was the end result, my 2000 FORD EXPLORER is doing the exact same thing in the heat... above 30 deg C.

Gave up on it - sold to Ford dealership that could not fix it. We had this problem with another Ford years ago - our local mechanic at the time removed the gas tank and replaced a filter in it - that solved the problem.
