Hi, I have a 1991 Honda Civic (5-speed) and it is a great little car...despite its mileage we have been told by our last mechanic that he expects us to get another 60-80,000 miles out of the car.

Recently it would not start one cold morning and so a mechanic came to check it out and ended up installing new spark plugs, which fixed the problem. The next day I was driving it when suddenly and out of nowhere a REALLY loud, high pitched whistling noise started coming from the engine. It lasted about 10 seconds and then shut off as suddenly as it had started.

Its been about 3 days since that first time and since then it has happened at least once during every drive I have taken...sometimes for only 10 seconds, sometimes for an unbroken 5 minutes at a time. The whistling occurs regardless of what gear I'm in, even when the car is in neutral or at a standstill. It seems to come and go randomly. Its new years weekend so NO car places are open here, but I want to know how serious of an issue this is! Should I still be driving it around?

Thank you so much in advance!

It sounds like one of your drive belts may be loose and squealing. Usually when you start it up first thing, the alternator belt will the culprit, since it wants to charge the battery back up.
