Just like the title said my car is throwing the CEL code (P0172 Fuel System Too Rich) and i'm not sure why. Here's a little background information:

Setup: D16Y8 with GReddy 19T turbo kit
Mileage:60,500

My car started missfiring on all cylinders so I changed my plugs/wires/cap/rotor. Since I have a turbo I have been using the NGK BKR7E. I reset the ECU to remove the trouble codes and drove around with my new "ignition system" for about 40 miles then a CEL went on again. I know that the GReddy e-Manage is setup to be rich under full throttle but when i drive around town at 40% throttle the air/fuel gauge shows that my car is running super rich.

My guess is that since it has been cold lately the fuel pressure may have been altered thus causing my car to run rich...

I'm not sure what's causing this so if you have any idea let me know. Thanks

anybody?

 

although I have a B16 18G turbo I keep getting code 45, I pull my plugs and they are on the richer side, as is my air/fuel gauge. The code only pops up when im curising part throttle every so often. I've asked other people with similar setups and they tell me that is just the nature of Greddy's piggyback computer.
