OK - truck was at idle for about 45 min. As i walked to the truck to get in the motor stumbles and the continues to run rough - I have replaced the injectors (250,000 miles and have never been done to my knowlege) replaced under cover harness and repaired the other harnesses. Checked the valve cover gasket ---ok--- now what ???? IDM (was done 3 years ago)

I read an earlier post on here by someone who was experiencing the same problem...turned out to be the IDM..if it were me, and I'm notorious for this when I can, I'd hit a wreaking yard first to see if I could find one for the same model/year. To me, logic would dictate that they'd be the same. If you find one, swap it out, if it runs fine again, then, if you want, you can buy another from the dealer...just a thought...
