This wire sends transmits a signal to 2 places: to the brain to tell it that you are trying to start the car and that the brain should richen the mixture, and to the cold start valve to enable it, in case the temp is below the trip point of the temp switch. It was probably taken off by someone who thought they could fix another problem they were having by disabling the CSV. This is usually NOT the problem, and fixes nothing since it does nothing, except when you are starting the engine, as long as it is hooked up to the right terminal. > and on another note, i stepped my idle up a bit (gen and oil light > flickering at idle) and the gen light doesn't flicker anymore. now the car > surges at idle until it is warmed up but i can deal with that if i don't > have to see any flickering lights!! I think people here have scared you with too much concern about your main bearings. I doubt that you have any greater main bearing problem than most of the rest of the list. > lastly, i've started thinking about the future of my car, especially my > engine. compression is good and i don't burn oil, but i do have the oil > light flickering at idle problem. so i'm told that my main bearings are > worn. what does this involve? what i need to know is, can i just fix the > bearing problem and keep my exisiting pistons/cylinders/heads/etc? or what > it be stupid to not do everything while the engine is out. The main bearings are the very last thing you can get to when you take the engine apart. By the time you are that far into it, you should look at everything closely to see what needs help. There is no substitute for looking things over with a critical eye and fixing what is wrong. The hard part is learning to recognize what needs help and what is okay. DON'T be tempted to just replace everything as a matter of course. This is invariably a waste of money and resources. It also demonstartes a lack of understanding (as in, "Well, I don't know what I'm doing, so I just replace everything.") I doubt that you have any sound reason to expect the other engine to be any better than the one already in the car. I suggest that you spend your time, and a very little money, coming to understand your FI system. This understanding will probably result in fixing some minor problems that have been bothering you. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Search old messages on the Web!
