Clean your mass air flow sensor. Its on the air filter tube. Go to the auto parts store. Buy MAF cleaner. Spray that chit down a few times. Viola. And change out your fuel filter as well.

Have you lost any power? If so change your fuel filter.

No its not the no mufflers. I ran with my front cats gutted with the stock Y and muffler unbolted like yours for about 6 months and got 20mpg on backroads (alot of hills) and 25 mpg on highway.

I wouldnt recommend using MAF cleaner, you might end up ruining your MAF altogether.
