spooled b16

My car is running like crap again. First it was hesitating and then surging kind of like if you were to let off the throttle and then slam it repetively to make it jerk back and forth. So I found out my fuel preasure was too high at idle like 50psi due to my fpr getting no vac. so i hooked it directly to the manifold and it brought fuel preasure down to 37psi and everything was fine.

Now 3 months later its doing it again and I don't know why, im not throwing any codes, but my a/f meter is pegged rich at idle like before sometimes at idle it will even die, it did this before as well until i fixed it and now its doing it again

any advice besides going stand-alone

Need more info but if it is just happing at idle try to clean out your iac motor

I cleaned out the iac a while ago, and all i have is the fmu no adjustable fpr and the injector size i don't know. I have heard people say the injectors don't look stock. It does it at idle and when i begin to go it bogs down like it's almost completely dead and then it surges after the bog. It seems to be doing it more often since i changed the fuel filter. hopefully i can get to my mechanic tomarrow
