Running rich and Idle problems

[Dinnertime]

I'm having a problem with running rich and a rough idle SOMETIMES. Its fine one minute and then it will drop and stall out. This all comes after A/c removal/valve ajustment (all in spec), plugs,wires,rotor,distrib cap. Any suggestions?

In order of my bet (not necessarily correct)

AFM, 02 sensor, ground. I'd check grounds, 02 sensor & then do an AFM. Do you have a CEL? if so what code?

[Dinnertime]

Throwing no codes. I'm new to E30's so im running into more and more problems. I don't know when the O2 sensor was last changed, but im going to test it before changing it.

Were are all the grounds?

Sounds about like mine was doing. Mine was the AFM and bad plugs.

[Dinnertime]

just changed the plugs.


I'm thinking its something to do with the A/c removal. It had fuel going into hardlines into a a/c line then back to the fpr on the rail.
