What can it be if rpm jumps...?

i swapped cars with my gf. so i dont put miles on my car. she has a 99 cl. this morning i started it and notice the rpm kept jumping up and down from 1 - 2.5. but when i shift it to drive it was ok. anyone know what's wrong with it before i bring it to the dealer to get robbed?

thanks,

is this common with the 2.3 too? My idle sometimes drops to like 4 or 500 and feels like its gonna die. Or is this an EGR problem?

I had the same problem and it was the ICV. Replaced it myself cause it seemed fairly easy.

Here's the install thread I made back when I did it. INSTALL

A brand new ICV at the honda dealer is about $100.
