Valve Rattle?
I am getting a slight valve rattle when accelerating. I use Sunoco 94, so there should not be a problem with octane. I also tried running through a bottle of Chevron's Techron fuel system cleaner but I still have same problem. Any advice as to what might be causing this?
Thanks

Hum, Not sure that stuff would get all the carbon. Have you taken her out for a good blowing out! Just tell the officer you were getting the gunk out! :jester
After lugging around it traffic, I get a little pinging when I open her up the first time or so, but it clears right up, after a couple of short WOT sprints. Now you don't have to take it to a hundred and gazillion MPHs, or leave $200 worth of rubber on the highway, just short aggressive sprints to say 80 or 90.

I think I know the noise you are talking about.. My car makes the same noise and it drives me nuts.. Sounds sort of like flutter/rattling.. Almost like a rocker arm is loose and its vibrating..
My car only makes that noise around 2500rpm and then stops once I go above that.. I have been so tempted to lift the valve covers off and check the torque on the rocker arms....
