The car runs great when cold, but after it warms up it loses power, jumps jerks. Basically acts like an old truck I had which had a choke and would do the same thing until I remembered to open it up once the truck was warm.

The first thing I would check is the coolant temp sensor really common for those to fail also the inside of the connector going to it see if the terminals are green or blue instead of silver?If they are you will need a new connector also. Its the bottom sensor with a black wire and yellow wire going to it.
