My wifes 2.2 engine stinks like gas and I can see liquid fuel on the tops of the injectors. I changed the o rings and I still have two leaking. Did I install the o rings wrong? Do I need new or rebuilt injectors? If you have done this job... have any install hints or tips. Thanks for any advice guys obviously I neeed to get this taken care of soon!

did you get the o-rings from a gm dealership? they might be the wrong size. or you might've knicked them. put a little grease on the o-rings before installing them.

I got AC delco o rings from the parts store and lubed the with motor oil before I installed them. Im not sure if they seated correctly though. Can they leak from anywhere else beside the o ring?

anythings possible. i would take them out and try again. if you forced everything back together o-rings might've been damaged or something else.

sounds like they rolled when installed. this can cause them to not seat correctly. if this is not the case then check to make sure that you are not over pressure. good luck.
