I have a 1992 240 with 199,600 miles (just replaced the alternator for the first time!) Recently, it has begun behaving strangely in the mornings when I start it up before work. It'll run fine for a minute or two before it starts to idle back down. It's always done that, but now it keeps idling down, all the way down. If I don't sit there goosing the gas, it cuts off. The problem persists 2-3 miles into my drive to work. Then it's fine for the rest of the day.
This morning, it cut out on me at a stop light. Immediately after I restarted it, it was fine again--smooth idle, no problems. Do you think this could be something like the voltage regulator? The more electrical accessories I have running (the turn signal seems to make it worse, along with the fan blower), the worse the I'm-Gonna-Stall Dance gets.
Also, it sounds like I have rocks rolling around in the trunk when I'm driving over a bad road. There is nothing in my trunk, and the spare/jack are tied down so tightly, they don't budge an inch. It's fine on the interstate--no funny rolling-rock noises--and handles as well as ever. I looked in the maintenance book my dad kept on it, which I have continued, and noticed that the rear shocks were replaced at 122,000 miles. I'm assuming this problem is the old shocks, but if anybody has any suggestions as to what I should check when I get under it this weekend, I'm all ears. Thanks!
