Thank you for the answer, i spoke with the tech support of the EFI kit and i 've been told to try a little thing to see if is a rich mixture problem related or not just by reducing fuel flow using a clamp or vise grip on the pressure hose.

I noticed the 3 bolts of the exhaust flange in between to pipe and headers a little loose, i guess that air can go in and mess up the o2 sensor wich is 2inches above, i guess that is air go in the o2 sensor would make mixture richer by sending a lean signal to the ECM, i need to test the car better.

Timing is now set about 12* (initial), but i will try to get it more advance like you said, tried to disconnect the vacuum hose and there was no difference at all at idle, any suggestion?
thank you.
