The new part didn't change the fuel pressure but the error codes haven't come back. 700 1991


I installed a new fuel pressure regulator (FPR). The output pressure is the same as the old one @ idle*** 39psi***. With the old one I had error codes (113 & 232) tripped w/in 5-10 minutes of starting the car. I have driven 2.5-3hrs now @ city/highway speeds w/ no codes. My pressure gauge is calibrated. I didn't change anything else between checking pressure w/ the old FPR & the new one.

OK maybe the problem is fixed but the process seems variable. When that happens it is nigh on impossible to troubleshoot stuff.
