Post by: dodgedude21 on November 22, 2005, 11:59:24 PM

sounds like they have a bad o-ring or one was left out or maybe in the throttle body?

lets start with what year and engine? the fuel injectors are basicaly electronicaly controlled valves switching from off to on letting presurized fuel out in a fine spray. did you get a fuel pressure gauge and check the fuel pressure? the regulator might have gone, you said you replaced the injectors right? are they leaking from anywhere?
