have the fuel pressure checked. it may be low enogh to cause fuel boiling when hot.
THANK YOU - WILL HAVE IT CHECKED
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.
NO CHANGE - ONE OF THE FIRST THINGS WE CHECK-OUT. THANKS FOR YOUR INPUT.
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.
