breathers? How much help are these breathers and what exactly do they do? I know I have seen some at pepboys. but how trustworth would that be from them? Where would a good place to get one of these?
I have the Billet one, used it for about a year. Then added some LT headers and just couldn't get my fuel trims correct. Thought about it for awhile and figured I would put the stock cap on. Lowered my fuel trims to where they should. So, I must have been getting some unmetered air going through the breather and into the throttle body. Wasn't a big deal, but probably will save me a few bucks a month in gas I didn't need to use from incorrect fuel trims. There are ways to bypass it so it doesn't do that, but I see no need to even have it on. I could just plug the opening in the breather and use it for looks if I wanted.
