Doug, You either have a problem in your acceleration enrichment circuit or you DeLorean needs a CO mix adjustment. To test your fuel enrichment circuit do the following: Start the engine and allow it to reach operating temperature. Access the engine compartment push the flap on the full throttle microswitch (parts manual 2/3/0 #15).
