You can find vacuum leaks by idling the engine and spraying carburetor cleaner along the intake manifold and accessories, listen for any changes/roughness in idle as you spray, they denote spots where leaks are.

Try disconnecting the battery for a full minute. The computer may need to reset and re learn the fuel tables
