So was just sitting at a light for 2-3 minutes and it picked up a weird idle like it was going down 50 rpm then back up. I gave it a little gas to 1,000 rpms and it would still do it. Rail pressure was fluctuating a little but it looked like normal. Could it be my low pressure fuel pump starting to die? What would cause the idle to go up and down like that? Now sitting at home in the drive way it won't do it.
