I am experiencing some idle issues with my 74 1.8 L-Jet. The idle is high for about 20 minutes and then comes down to around 800 rpm once the engine is good and hot. Up until then it will idle around 1400 rpms. I assumed there was a vacuum leak so I went through everything and even did a pressurized smoke leak test. No leaks.
Next up was the AAR. I have collected three and bench tested all of them. They all close up in around 3 minutes which seems about right. All work. I tried one afeter the other and same results. I thought about it for a bit and it seems once the engine is hot enough it closes the AAR from the heat. This lead me to test the voltage to the AAR and yup NO POWER ! Harness looks fine. Any suggestions where to start tracing this? (IMG:style_emoticons/default/idea.gif) I am currently driving the car with out the AAR and it has idle trouble for about 3 to 5 minutes, after that seems pretty stable. |

I replaced my throttle return spring on my throttle body and that seemed to help,as it idled all over the place sometimes.
I also replaced the gasket on my oil filler tube,this also seemed to help. I also replaced my rubber tube from the AAR to the throttle body,auto atlanta just made a order of them,as they have not been avalible for a long time. I have a 74-1.8L also. If you pull the oil filler cap off when its runing it should stall out. I am New to the 914 crowd,so just trying to offer some help. My best mod on my motor is the Mallory 4554101 optical distribitor really expensive but absolutely amazing how the car runs now. Good luck with finding the problem,sorry I cant be more help. If you figure it out and have some time I would like to see a couple pictures of your motor,as I have no idea how to configure my heater lines. Thanks. Grant |
