Hey...been a minute (or a few years) since I posted but I have an issue that I really need some help with. First, what is the module that sits on top of the fuel pressure controller? Second...my Z began stalling HORRIBLY and cutting off at idle at every stop light. Also running pig rich. I changed out the fuel filter, FPR and the Dampener, Fuel pressure is 38.5 psig. (I don't think it's the fuel pump) Injectors all ohm at 13. IACV, TPS (.45) is within spec also. MAF's - good, CAS and PTU, good. Could my Fuel pump controller be dying slowly? I'm fresh out of ideas. Any help would be greatly appreciated. Thanks again.
