All,

I have traced a vacuum leak to my injector seats. I did replace them with billet ones from verdict, but one of them is still bad (due to installation error on my part). I will be replacing the faulty one soon. Question I have for you guys is, what do you think the increase in fuel economy will be once I replace the seat and have all the vacuum leaks fixed. I currently am only getting 21 mpg mixed.

Thanks!

No way to know for sure. Mileage might even go down.

What are your long term fuel trims presently?
