Just got my car back from the mechanic where i thought i blew a head gasket but i actually crossed a vacuum line with a coolant line when i went to put in a skunk2 manifold but subsequently took off. The stock mani got filled with coolant while the coolant was getting gas fumes injected into it. A new stock intake mani was put on it but now when i start up my car itll shoot up to 1.5K RPM which is normal, glide down to 1K which is normal, then itll like blip down to about 500 like its about to stall then itll be fine. Any suggestions b/c im tryin to trade it in for a newer car and i want to get the most money out of it while not having some sales person asking questions about my car sounding funny. thanks

i forgot to say that if its warmed up it seems to not do it as badly as when i start it cold.
