I recently did a bunch of work to my Cobalt, which involved removing the fuel rail. I fixed all of my problems, but my idle went downhill. I heard a hissing noise coming from around the intake (so I thought), so I removed the throttle body and intake manifold to check out the o-rings (which were new). Everything looked ok, so I cleaned surfaces and reinstalled.
I started the car up and immediately heard the same noise again. This time I realized it was coming from the fuel rail. I placed both hands on either end of the rail and pressed down with decent force. The hissing stopped, and idle returned to normal; however, the problem persists since I don't know how hard I should be pushing these injectors back in....
So, how much force is needed to properly seal the injectors?
Thanks!
