Engine hesitation problems - Pleqse help!
I drive a 2000 Ex V10
My truck has been having an issue at idle after it warms up, almost every time after it sits and cools down.
My problem is that once the truck warms up, it will drop down to 500 rpm's and will have a hesitation/miss/lope for about 20 seconds. When it does this I can hear the exhaust making a sputtering sound. On two occasions during windy rain it would hesitate while driving but then straighten up within a half mile or so and be fine. I have changed all the boots, cop's and plugs and don't think that is where my problem is.
What I can't figure is why it seems to hesitate/lope once it warms up!
Anyone have a suggestion or have had this problem not related to a failing boot, plug or cop?

Check for vacuum leaks? Maybe the elbow where the PCV is attached to? Do you have EGR?
Clean your MAF and reset the computer while doing it by disconnecting the negative terminal in the battery. Doesn't hurt to do it and it should be done periodically.
