I just did my timing belt and started it up, let it idle for a min and turned it off. I could smell gas so i started looking around the injectors and it looks as if one is leaking. middle injector on passenger side.
Now i'm running K04's on a stock trim (I'm not chipped) What are my options as far as injectors go?
What are the specs on the stock injectors? lbs or cc's?
would it be best to replace with OEM, or is there something i could put that would be benificial without it being chipped.

Thanks
