Running rich@idle
I'm having a problem with my car running to rich @ idle.
A/-F is 11.4 and I can't seem to get it any leaner.
Fuelpressure is @ 32psi, I can get it richer with the commander but can't get it any leaner. What could be the problem?
-leaking injectors
-bad fpr
-bad fuelpump
-bad pulsationdamper(saw that the bolt had come loose)
Any help is welcome.

How big are your primary injectors? This is pretty common with the 850's. Try searching for "850cc" or "850 primary" or something like that.
Basically, the Powerfc has a minimum on time for the injectors. The only solution, as far as I know, is to increase the negative lag until the idle afr is good, then retune the rest of the map.
This assuming that it is the powerfc causing this and it isn't a mechanical issue

I'm think they are connected in the right way, think that maybe the fpr isn't working like it supposed to, before it was set @ 3.5bar and I lowered it to 2.2bar and the A/F went from 11.4 to 13 but after that the car would'nt start anymore and i found out that the bolt in the pulsationdamper had come of.
