Possibly a vacuum leak. Check around area where work was done for loose or broken vacuum lines or wire harnesses.

Also check the main ground strap from the engine to the frame. You may have broken it when jacking up the engine. Also check the connection for the Crank Position Sensor on the distributor. You may have smacked it against the fire wall and knocked it loose. You just want to replace it also. https://www.youtube.com/watch? v=TEuzGJKExks
