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??
Thanks.
