car drops RPMs on starts

when i start it i jusmps to about 1800-1900 then bogs down to like 900, then back to about 1400-1500. this never happened before. it usually went to like 1800 and stayed till it slowly came down. what could it be?

Could be your throttle body.

Idle-Air Control Valve is my next guess. But an ignition coil is known to cause a similar problem from what I've been told.
