Ok i removed my JRSC from my b16a1 cus i was sick of the terrible gas mileage without it being tuned. I put on a b17 ported and polished intake manifold, and left everything else the same. Now i am still having the same fuel problem as i was having with the JRSC. I am burning REALLY rich. I am getting about 100 miles to a tank, which is a little bit better then the JRSC. So i replaced the O2 sensors, and the map sensor, and the rotor and cap (cus that went bad) and am still having the problem.
Somebody please give me direction and an idea on where to go next. I need to get this one fixed before i start my next project.
thanks

 

Are you running an fmu, larger injectors, or an extremely high fuel pressure?

 

No FMU, stock b16a injectors, stock fuel pump, and not sure about the high fuel pressure, but i don't get a large amount of pressure when i release the fuel cap.

 

Maybe one of your injectors is stuck open..Can you try another set of stock injectors.?...I am really pulling at straws here because most of my suggestions you have already addressed.

 

i have some 440cc injectors that i could probably try, but that sounds like it might be a possibility, cus sometimes when i've gotten on it hard it sounds like the fuel might be blowing out the spark. but the 440cc injectors flow harder then the stock ones right? and other ideas are welcome

 

Figured it out, I had a map sensor vaccum line hooked up wrong, i think it had to do with my fuel pressure vacuum or somthing, also, my PCV valve wasn't hooked up, and i had a hole in my fuel pressure regulator vacuum line. Once i fixed those everything worked.

 

Glad you figured it out
