I recentlly noticed a random clicking sound (random and sparatic, not
like valves) that is only present when im coasting with my foot off the
gas. As so as I touch the gas, even the slightest bit, the noise
stops. Engine was warm when the problem was noticed. Temp reads
normal, normal revs at all points.
Also, perhaps related, when I put the AC on it will run fine for a bit
then make a horrible sound like a dying girrafe (if you saw the south
park movie its almost exactly that sound).
