Sounds like either a bad sensor, like an 02 sensor, or perhaps a throttle position sensor, or malfunctioning fuel injector. If it is carbureted, you may need a carb rebuild.

OK THANKS, WE HAVE REPLACED ALL THE SENORS IT HAS.PUT NEW FUEL PUMP NEW COMP. NEW TIMEING CHAIN AN GEARS. GOT INJECTORS OUT OF ANOTHER THROTTLE BODY.IT WILL IDLE FOR FIRST 2 MINUTES THEN STARTS RACEING UP AN DOWN. LIKE IT RUNS LOW ON GAS. THEN WHEN IT DOES IT STINKS.DONE WORKED ON CONVERTOR. THEN BLACK SMOKE COMES OUT OF TAIL PIPES.
