check the codes. use the link in my sig. i'm betting you have a boost leak though... check all your piping connections.

its throwing a code 14

do a search for code 14 and there are 25 pages of threads about this. You should be able to find your answers there. If you have anymore problems someone will help you...............lol

thats an ignition code. reset the code by pulling the efi fuse in the fuse box under the hood. pull for ~30 seconds and replace. see if the code comes back. usually that code wont happen while driving. its when you try to start it w/o an ignition signal.

aside from the code, it sounds like you may have blown off an ic pipe. check all piping and couplers.
