Been havin a bit of a problem with my xr6 lately, when I give it a boot from the start its feelin like its strugiling for fuel, starts splattering and feels like its going to die, but once I pick up a bit of speed it stops.. cant even get the wheels spinning anymore.. any ideas what it would be? its had injectors and cooler done, making 330rwkw on a 12psi tune... time 4 a new fuel pump maybe?? cheers..
