Ok, long story short a new plug wire set was put on the car, and I recently re-tuned the car (last Sunday), modifying the position of the throttle plates from being a tad bit open to being completely and totally closed when the car idles. Here we go: Today, I was driving at about 45mph with the temp gauge near 160 (unmarked line before 220), and I made a sudden stop due to a car stopping in front of me. Well, when I did this - my car died. I restarted and figured it was a fluke. I did it again just to test it - 45mph and sudden stop - my car died again. So I waited until the transmission fully shifted into 3rd (auto tranny), and slowly came to a gradual stop. When I did this, the car downshifted from 3rd to 2nd well, but from 2nd to 1st - when it downshifted - the rpms jumped down from 1000 to 500 and then shot right back up to 1000 - so suddenly my battery and oil light came on and off as if the car aaalllmosttt lost it. Also now, if I mess with the mixture screw at all - lean it or enrichen it - when I pull the allen wrench out of the hole, the car will die every time. I haven't messed with it in forever - but considering the nature of the car and practically having to retune when doing a tuneup, I had to adjust the mixture screw, and that is how I found this symptom (one of my plug wires hadn't been firing so this adjustment was necessary considering I don't run the lambda system at ALL). When I drove home tonight, I noticed my battery light was just spazzing - flickering extremely rapidly. I got out, wiggled/tightened the power plug on the side of the alternator, and the battery light stopped flickering. After I did this, all the symptoms of the car dying (minus tuning the mixture screw) seemed to disappear. Keep in mind, this was less than a 1 mile test drive as I was in my neighborhood and it was about 1am so I couldn't do a full test drive/stop-go conditions, and the car was a bit warmer than earlier when the symptoms were prevalent. Could all of those symptoms have been caused by a loose electrical connection to the alternator and the engine wasn't getting adequate power to deal with the sudden stops? This is a new one for me, and maybe all I need to do is reposition the throttle plates where I had them for the last two years. I don't like the car dying like that in the middle of the street due to a sudden stop. That's extremely dangerous... Jeremiah __________________________________________________ Do You Yahoo!?
