running rich

[Brandon Rogers]

oh yeah I also did the O2 sensor - forgot I did that obvious one... 
 
What would you suggest WRT to the ISV - clean it?  How would that affect
mixture?  
 
MFTS - mutherscratcher - and I just had the IM off, too....
 
thanks Kneale-

Your O2 sensor,  your ISV, the multifunction temperature sensor and,
possibly, the reprogramming of the ECU could all contribute to rich
running, I believe.

Guys-
Trying to correct a rich running car-
Stock 3B although running RS2 turbo and EM and software.

In the past year or so I have replaced the coolant temp sensor in back
of head and fuel pressure regulator. I pressure tested the system
recently and the F5DPOR (I think thats correct) plugs, cap and rotor
have less than 20k miles on them. 

I plan to swap in some different injectors in the next couple days.
Other than software - what else would cause rich running?
