Hi,

well had this problem for a while but havent really had time to work on the car until recently.

So the car starts and idles not too bad

but if i press the throttle it either dies out, or struggles trying to rev (really rough).

car has a brand new supra fuel pump
new fuel pump relays
new fuel filter
compression is good
tested 2 sets of coils and igniter
tps was in spec

i just put in a fuel pressure regulator today though and the gauge on it is really low 15-20 and the screw at top wont let me adjust it any higher. so im thinking either the new pump is bad or the new fpr is bad?

any help would be appreciated
