i have 1 injector thats leaking what could the problem be? and any pics or info on how to change the injector

 

were is it leaking at, under the fuel rail or were the injector sits inside the head?

 

changing an injector is very easy, unclip the harness, unbolt the fuel rail and pull up.... the injector is held in the intake manifold with a rubber gromet on the manifold and an O-ring in the fuel rail. if fuel is actually coming out, it's got to be the O-Ring in the fuel rail. the grommet in the manifold wouldn't leak fuel out, it'd just be a vaccum leak. that O-ring is going to cost you a pretty penny. maybe as many as 2, or three hundred pennies actually. If by "leaking" you mean it's leaking fuel into the head and you have one cylinder not atomizing fuel, then you could have it cleaned, but replacing is easy, just three nuts hold the fuel rail on.
