I've got a friend with a 95 Cavalier w/2.2L and the first cylinder
(closest to the fuel pressure regulator) seems to be leaking gas (to
the outside). We've tried pulling the injector and replacing the
o-rings, but to no avail. (We also pulled one of the other injectors,
replaced those rings, and it sealed back up perfectly, so I don't
think that I'm doing it completely wrong...)
Any ideas what I should try to fix the leak?? Would a faulty injector
exhibit this? Or, should I be looking at the fuel injector bracket
being bent (and pulling that injector out slightly)?
Any other suggestions??
