Hello,
I am sure this has been discussed before. Sorry to post without looking for previous discussions. My car has been Idling a little weird when first starting up but then fine after a few miles/minutes. At first I thought the computer just needed to re-learn since it has been inop for 2yrs. But now I am thinking sticky IACV.It idles about 1100 when first start up cold surging only minor amounts-not a problem. Most obvious when engine is warm-shut off for 10 minutes- re-start...that is when it surges the most and labors a bit to start. Surges from 500-1200 rpms. I replaced all hoses and sealed everything up real good when I put it all back together so I don't think I have an intake leak. Injectors are all fresh as well. Thanks for any help. Art |

Art, i am only making an assumption here. I believe the test is with a DVM (digital volt meter) set to Ohms. Pull off the connector, place the 2 meter probes on the 2 terminals and measure the Ohms. When cold you have one value, when the engine is warm, you have a second value. Not sure what the cold-hot values are, perhaps someone can help out?

Thanks Alan,
I am now driving my '79 Fiat Spider until it sells then I will bring the BMW back out to drive it again, so it may be a while before I worry about the issue. I do have the good manual so I am sure it spells it out well. Once I am back to driving the car again I will certainly be posting more questions.....and I will learn to post more pictures. Art |

Sold the Fiat a couple weeks ago! So I am now driving my car daily. I figured out my "surging idle" problem. It was simply the stop screw on the throttle valve. It was holding the throttle valve open a bit too much, re-adjusted it and "all is well".
Hopefully I will have some time to start working on the car soon. |

Hi Al, the values are 3000 ohms when the engine is cold, and around 200 ohms when the engine is warm. ---------------------------------------------------------------------------------------------------------------------------------- E30'S AREN'T BUILT, THEY'RE CAUGHT IN THE WILD!!! When in doubt, use full throttle, it may not improve the situation, but it will end the suspence. |
