OK, so I removed and cleaned out the fuel distributor......I put it back, but now my idle is off.
SHould I have expected that?
How do I get it back in line? (please post the "for dummies" version) |

I'll bet someone like jrcook or Ken will have the perfect answer, but while you wait I would follow the instructions on adjusting fuel ratio by ear to get it as close as possible.

Back one step....where is the allen key adjustment located. I have never done this on a K-Jet. My Baur used to be a carb model. This 323i is K-Jet |

it's right between the fuel dizzy, and the air boot next to it. you will see a little pipe(it might have a little cover/plug on it, take it off), the screw is down there |

if its like the m10, you will need a very long 3mm(?) allen wrench. Sorry, know little about the m10, and essentially nothing about your super-awsome m20s... |

what do you mean by "cleaned out the fuel distributor"? The fuel distributor itself can't effectively be taken apart and cleaned.
Do you mean the air flow meter (AFM), aka sensor plate? That is the aluminum "box" that the fuel distributor bolts to.
Depending on what you did you could have caused lots of problems. Did you seperate the fuel distributor from the AFM? If so you could have a vacuum leak a the O-ring seal between them. Did you seperate the top and bottom halves of the AFM? This could also create a vacuum leak if you didn't use a new gasket.
Did you use any solvents to clean the afm out with the FD in place? If so you could have left dirt/grit on the plunger rod which can ruin the FD over time.
The AFM needs to be clean and properly lubricated, and the FD plunger rod needs to be spotless. You may also have disrupted the centering or hieght of the sensor plate. Check the adjustment. Once that is ok then the mixture likely needs to be readjusted.
It will be much easier on the 323i than the 320i due to AFM location, all you need is a long 3mm allen.
cw enrichens, ccw leans. Adjust in very small increments to highest idle get things close. |

The only thing taken off was the fuel distributor. It was off the car to have fuel injection cleaner sprayed into the holes, and into the pulnger while I make the plunger move up and down.
I touched the flapper's bearing to make sure it wasnt scorred and to make sure it turned freely. I then sprayed it with WD-40 to clean it.
I made sure to put the o-ring that goes around the plunger back in place. The only thing missing was a single brass washer from one of the big ports on the side of the fuel distributor. I lost that somewhere in the engine compartment.
I am pretty sure that the three flat head screws are on tight. Other than that, I dont know what else needed to be done to prevent a leak between the fuel distributor and the flapper housing. |

It sounds like you took care to do this properly. Assuming all else is equal and any injector cleaner has now been flushed from the system, this is likely as simple as the idle speed or mixture just needing to be readjusted. Removing the FD could have been enough to change the position enough to have an effect on the mixture, and thus idle speed.
Does it idle faster, slower, or have a loap or miss that it didn't have before? If it otherwise runs good, just adjust the idle speed to the correct rpm. |

wait a minute, i just reread your post. The washer you're refering to is copper and is necessary to keep connections from leaking. I'm suprised you don't have at a minimum a fine mist of fuel spraying all over your engine bay. A leak like that could have an effect on fuel pressure and thus idle speed, as well as be dangerous. Do whatever it takes to find it again, or find one off a volvo, vw, audi, e21, or porsche in a junk yard.

It was idling low, and sputtering to a stall. I adjusted, it is idling at about 6,500 or 7,500 with a sputtery response.
I only messed with that allen key between the fuel distributor and intake boot.
Can someone point to the other screw I should be messing with?
There is no mist. I can see that it leaks a little towards the firewall/wheel arch.
Is this a washer that can be bought at an auto parts store? |

Replaced the washers, and that immidiatly did away with the rough idle problem.
Man, these little things are about the most important parts on the car. They keep gas from leaking out and creating a hazard, and air from leaking in and disrupting engine operation.
I am hoping that replacing all the ones that were missing.......seems like there was one or two missing prior to me......may fix cold start problems.
Also, aluminum wont cut it, and neither will an off size. those things have to be copper, and they have to be the right size. I tried an aluminum one that a Mercedez guy gave me, and it was like Niagra fuckin Falls of gas spewing out! |

Any update to this? Did you get it running like you wanted? For future reference, there are two sizes of copper washers for the fuel distributor. Just take them in to a hardware store like ACE Hardware and match them up. While you are there, take a look around at all the cool stuff that you can buy there much more cheaply than BMW or mail order. |
