Its not the o2's. I unplugged them today and it didnt make any difference.

A thing I noticed though is that my fuel pressure is around 35psi at idle and doesnt change much when its reved. If I pull the vacuum line off the regulator it jumps up to about 45psi. Which is where it SHOULD be, right?

I'm also wondering if a loose rocker arm would cause this? I'm beginning to hear a slight ticking at idle.
I'm just trying to think of any possiblilty cause i REALLY need my car back running since its been sitting for close to 2 months.
