Gross Polluter ... ;(

I know it already passed, but as mentioned, those Mustang injectors could be the real culprit. If thats not a stroker I think I would ditch them for some oem's. The numbers all scream RICH to me. Also, never skip on a fresh oil change before a smog check. HC's build up in the motor oil and can have a pretty negative effect on your numbers.

They are the same LBS and flow as stock injectors, the only difference is they are 4 hole to make it atomize better.


Here is the before and after:

Okay. I assumed they were bigger and thats why you had them. My mistake.

So out of curiosity, did you gain anything noticeable by changing them? Power? MPG?

It does have better throttle response and mileage has gone up, but i swapped them right after getting the head rebuilt and i had some leaky valves...
