Check out this FAQ article to narrow down the causes and get more clues. It could be anything so the more information such as error codes and sensor readings you have, the better guesses you'll get.

don't forget to check for a cracked hose and loose hose clamp, is it studdering? And the ECU hose.

no studder runs and idles fine just revs when first start
