Hi Everyone,<p>I have a 1980 244 DL.<p>Yesterday, Friday, April 17, 2009, I was driving around doing errands, but got stuck in a bottleneck during rush-hour traffic (took ~45min to move 2 miles). This was also the first real "warm" day of the year (78 degrees Fahrenheit).<p>While stopped at idle at about the 1.5 mile mark, I noticed a new buzzing/rattle-type noise that could be heard separately from but in addition to the normal hum of the engine.<p>I couldn't locate the source of the sound. And, when driving, I was unable to hear the new noise, so I don't know if it disappeared or was just masked by the engine/road/environment noises.<p>Before heading home, I made one last errand stop and while pulling into a parking space, the engine cut off and the instrument panel lights flashed on. When I turned the key to re-start the engine (so I could fully pull into the parking spot), the engine started right up and no instrument panel lights turned on. <p>After returning to the car about ten minutes later, I did a general look-over check (around the car and under the hood) and noticed nothing unusual. The car started right back up and made the trip home (about 5-7 miles) without further incident, but continued to make the new buzzing/rattle-type noise that I only heard at idle.<p>I have not started or driven the car yet today.<p>---<p>I'm not sure if it is related or not, but I had a prior issue a couple weeks ago:<br>On Saturday, April 4, 2009, my car wouldn't start. <br>I had it jump-started, drove around for ~20 minutes, and then went to a local indy shop (not my regular shop, which is closed on Saturdays) to test the battery-- the results showed that a new battery was needed. One was ordered and installed on Tuesday, April 7 (the shop is closed on Sundays and Mondays).<p>---<p>My regular indy shop will be open on Monday, but I was wondering if you guys had any thoughts/ideas about what this is or could be.<p>Thanks for your time,<br>volvie!
