Ok when i first start up the car and it's cold, it wants to go like right away without me even touching the gas, like the rpm will jump up it will do it like a couple times and than it's ok. Also my idle has been acting a little funny, so it could be the spark plugs or the timing i'm guessing?

have you pulled codes? done a tune up lately? listing a sig would help (mods etc). cleaned the IAC lately? what rpms does it oscillate at?
