Arg, Sorry I made a mistake, I accidently typed d16z6, When in fact its a d16a6 (Sorry about that), Firstly Its not an Si ECU, Its another DX ecu, Secondly, the two present injectors should be able to support a 00.1 difference in displacement.

I just replaced the fuel filter today, in hopes that mabye it was the fuel pressure (Or the lack there of, No hiss or anything when you released a fuel line, or opened the gas tank) But unfortunatly, My friend was playing with the timing (Jumping it a notch both ways) to check if mabye that was the problem since people were saying the timing was off due to the fact that the intake hissed REALLY loud, and you could hear exhaust gases through it. But back onto the subject, I was trying to loosen the tensionor bolt, and it stripped so bad I can't fit a 14mm on it anymore. (Any sugestions for getting that off?)

Now that I have cleared things up, What do you think it could be?
