Yes, I guess I should have mentioned that. I am at sea level here in
Washington, and was at maybe 300 feet down in CA. I'm guessing that the
problem is the grade of gas. I'm just wondering what is in that CA gas
that makes the truck run so much better, and if there is something I can
put on or take off of my Dakota to make it happier here with this WA
gas. I probably got some CA specific smog stuff on my truck that I
don't need now that I'm in WA.
