Hey guys, in my 88 today, i noticed a hissing sound (like a snake) from the engine. i'm 75% sure its the injectors. i took the injector rails out and put some additional O rings on the outside, hoping that would seal them but i had no luck. help?

 

Did you check all your vacuum lines?

 

Yes, i did not find anything. today im going to try the carb cleaner trick and see what happens.

 

found out that one of my vacuum lines had a crack in it. thanks for the heads up
