So heres the situation. I'm trying to get my emissions done on my Type R but i'm throwing a CEL for code P0172 for the fuel system running to rich. Anyways we are trying to diagnose the problem as we believe my fuel pressure is fine.

We believe the problem is with my fuel injectors as I tried a different setup when I took the supercharger off my Type R. I had DSM 450cc's in it when it was supercharged so instead of rewiring it back to my stock Injectors and found some N/A DSM 240cc's and thru those in. We believe they may be the cause of my CEL and also found 2 of the injectors nozzels are cracked.

Now onto my question. I no longer have my original stock OBD2 240cc Injectors. I do however have a set of OBD1 240cc Injectors and clips that I could wire in in place of the DSM's that are in there now.

Will my car be fine with Running these OBD1 injectors. From what I understand is it should run exactly as the OBD2 Injectors would assuming the clips are wired correctly as the only difference between the OBD1 and OBD2 injectors are clips on the injectors themselves.

Anyways I just wanted to verify if this is correct before I wire them in and they dont' work right then have to redo it for OBD2. Please help me out with this as I have to get the car to pass emissions by the end of the month.

 

running stock obd1 injectors are the same as running stock obd2 injectors. just rewire them correctly and you should be good.

 

What impedance are the injectors, low or high? (peak & hold or saturated)

What OBD they are won't have as much of a baring on how the car runs as whether or not they are low or high impedance will. DSM injectors are low impedance (2.5-3 Ohms w/resistor box) most OBD1 Honda injectors are high impedance (12-13 Ohms w/no resistor). Except for the OBD1 Accord and Prelude injectors.

 

X2 depends if its peak and hold or saturated other tahn that if you have saturated then you should be fine if you have them obd1 peak and hold you are sir in need of a resistor box.
