took the truck in for the 2nd time about the idle. 1st they checked for codes. Of course no codes. This time they searched through Oasis and couldn't find anything about it. I even suggested to the service rep to reprogram my computer.

So if anyone has the exact TSB#, I would appreciate it.

thanks

Check the following thread. This fix for the rough idle problem has worked for several of us.

thanks for response. I forgot to mention that I tried moving the harness as well as the Texaco gas. It's still there but not as harsh.
