Has anyone experience this? I only have 37K miles on my path and it seems that when stoped at a light, or on park, the idle is rough and the truck shakes. I can tell that the RPM is slightly above 500, and when I first got it, the RPM on idle is around 800. Seems to soon for a tune up wouldn't you agree? Anyhow, I have 30K service coming up and hopefully they will be able to fix the issue.
--btw, this all happend right after the install of the Airlift 1000.
