3.2 DME stalls on rainy days
My 87 3.2 stalls on rainy days. It happens when I push in the clutch (as in downshifting or stopping for a red-light). I ahve changed the idle speed stabilizer. Any other thoughts??
Other than this, the car runs perfectly. It also starts back immediately and experiences no stumbling or missing. Thanks, Scott |

Scott,
Try swapping out the ignition module. I used to work on other euro cars with DME type injection and problems such as yours on cool, rainy days were often caused by this. You may also want to check that proper power gets to the automatic idle control motor (idle regulator). (Sure sounds like classic symptoms of a bad idle reg -- did you replace with a new one? --Most all of them go bad at some point) There is also an engine temp sensor on the engine somewhere. You may want to check this too. Also check the resistance on the flowmeter. All of these things can be common problem areas on pulsed injection cars. Hope this helps, Nick. ------------------ __________ Nick Shumaker 1982 911SC Coupe |

I had idle problems recently cured by electric cleaning spray!.
Cheap and worth a try as it can do no harm!. Remove and spray all electric plugs/sockets in engine bay inc. the head temp sensor which is the white plug on left side of engine bay (there are 3 in a vertical line, white on should be on top) hope you are as lucky as I was Rgds Ben |

I think I know what the problem is on this one, as I just found a remedy for it.
The air flow meter has the DME plug in. It's the black 4 prong outlet going into the air box meter. It has 4 screws. They make contact with the circuit inside by sliding in...they're not soldered or anything of the sort. I took mine out (just take off the air flow meter to do this), put it back in and was able to make it Worse, which was good. Then i took it out, bent the little leads down a bit, and made sure they slide in and made a good solid contact. That helped greatly. Also, if that hadn't worked, I'd have disassembled them and soldered them into place...better than buying a new air flow meter. |

Before throwing more money at the problem or doing anything more complicated I would have my base idle and CO checked.
