My D has been sputtering since I got it- I found a loose connector in the bucket with the windshield washer bottle, and a really bad ground connection underneath the air filter - other sputterers might want to check these things.... anyway, I need more help. I was driving down the highway when my 'cruise control' kicked in. THen I remembered that the car doesn't have cruise control! I put it in neutral and found that the engine was naturally revving at 5k RPM. I thought it was a stuck accelerator, but I checked it and it's not. THe butterfly valve seems to be fully closed. The frequency valve, I'm not sure if it's working, but it could just be becuase everything else is so loud! What are the symptoms of a frequency valve not working? I thought the frequency valve not working would lower the idle.. that's what it was doing before.. Is it important that the frequency valve is oriented up/down? The car does not idle well at all, also. When idling (will only idel with idle screw adjustment), I disconnected the idle speed regulator and nothing changed... I suppose this is bad... THere's so much stuff to look at that isn't working right I'm not sure where to start... Any ideas? Thanks in advance... Jim 1537
