Rough Idle ???
I started my psd up today and it idled rough for about 2 or 3 minutes like a gas engine with a bad plug wire. it did this before but hasnt did it in along time once it warmed up for a couple of minutes it went away and ran smooth. what could cause this.

Yup it definately sounds like a GP issue. Try cycling the GP's a bit longer before starting. Let them heat even after the wait to start (WTS) light goes off. It is probably doing it because it is getting colder. The GP's will run for 2 minutes before they kick off. If it still does it what I do is let them cycle for 2 mins. and turn off ignition and let them cycle for a bit longer then start.
There is a w ay you can determine which one is going out you will need an ohm meter. Also look at the UVC connection at the valve cover to see if the connector is burnt.
