well, during cold starts, it should top off around 1500K and then settle down.

it is NOT normal for the needle to dance between rpms. a sign of a blown fast idle valve is that it'll feel like someone is rev'ing the engine, but your foot isn't on the pedal.

a cracked PCV valve will give the same symptoms and it's worth it to look into it. the part can be purchased at autozone for $3.

my fast idle valve went out last month and it sucked. :down:
