yea thats one thing that i havent replaced yet. are the vtec and ls same? well the fuel pressure should tell me whats my pressure right? what should the pressure be for a b18 vtec? i also have a 96 gsr that i put a head on and its doing the same thing. runs good on idle but when i rev it up or go to drive it its acting up, if i floor it form a dig it seems like it choking at some points and once in a while it will get that lil rip of power and go then after it jerks like that it boggs down again.

one thing i should ask when i am setting up my timing by the 1st cyl when i set the 1 cyl at tdc do i set the cams when the cyl is at tdc on its way up or on its way coming down? hope i explained it right.
