I just bought a 2002 Caravelle interceptor with the 5.7gsi and it will idle perfect and starts fine, but will not rev up. On the muffs it seems to rev a little higher than under a load. I was wondering if somebody could tell me what the high pressure fuel pump should have when you throttle up. It holds 30psi idling but when u try to reach wot it drops to 4-5? Any suggestions would b greatly appreciated thnx
