system too rich...
i'm sorry about a noob question, but i'm very new to engine work. i've been running a t3/t4 turbo for about a month now, the cel just came on and reads system too rich (P0172). the noob question is, "too rich" does that mean too much air? if so, how di i adjust to compensate for that? thanx in advance.
edit: also, another code appeared at teh same time, idle control malfunction. could the two problems be related, one cause the other or vi versa? any help would re appreciated. thank you. /d Last edited by KrazyD; 10-21-2004 at 03:21 PM.

too rich = too much fuel in the mix; unfortunately, i don't know enough about boost setups to know what controller you'll need to adjust the air/fuel mix.
you'll get more help if you describe the application/engine (and fuel system), and if this is boost related, it might get more attention in the turbo forum. yes i believe that the 2 could be related: improper fuel mappings in certain rpm ranges, but that's just a shot in the dark; I'm sure one of the veterans will have an answer...if you can be a bit more specific about what you're running.

Hondata + Tuning = problem solved. Plus you'll have more power after tuning.

I agree with prelude.
what kind of FMU do you have ? unless its a "standalone" then all you can tune is fuel and no timing. if its only a fuel thing then i would recommend changing to a "standalone" that can tune timing
