Hello, I have just installed a dynomax muffler on my car. Now my car hesitates or sputters a little when i first give it gas. Not very much, but it didn't do this before. I think i remember reading that when you put a free flowing muffler on the car you have to mess with the air and fuel adjustments. If this is right, should i adjust for more gas or less. Or is it just a trial and error type deal. When the car is idleing the frequency valve is buzzing. It just hesitates when i first give it gas. Any ideas. Thank you.
