Hello, just got a 93 HB Civic with a b18b1 engine swap. In the morning when I start the car it seems like the choke went bad or something. It revs high and low high and low until the car warms up. Anyone know what this is and or how it can be fixed?

Are you using a Hondata system?

with the car cold remove the intake tube at the throttle body and start the car. place your finger over the lower hole on the firewall side of the throttle body bore. if the oscillating idle stops you need a new cold idle-up valve. that is the most frequent cause.
