put an o2 sensor that you know is good in it.. so it doesnt run rich all the time..
i dont know why you wouldnt run one?!?

check the filter on your maf... if air doesnt flow the same all the way around it ,, it will run shity.. mainly at idle though..

make sure that none of your injectors are leaking..

start with a fuel pressure gauge..
start the car..
turn it off..
see if the pressure drops..
if the pressure bleeds off..
it is eather a bad injector or fuel pressure regulator..

if not pm me..
