'82 380sl - Intermittent loss of power when the gas pedal is depressed
Hello All, a plea for advice/ help.
My beloved brown 1982 380sl has developed an intermittent problem over the past few days.
Half the time, the car is operating exceptionally well, _except_, when it is in park, the idle speed is around 1700rpm. I've been living with the idle problem for a month or so, trying to figure it out but not considering it urgent, until...
The other day, the car started to spend the other half of the time with some ver strange symptoms. The idle speed in park is down to what I believe is normal (800-1000rpm), but when the car is in gear, and especially moving slowly, if I press the gas pedal more than a tiny bit, the car stops accelerating, and power drops off completely. It stays like this for a few seconds, shudders a bit, then power picks back up.
Pressing the pedal all the way to the kickdown switch will get the car to shift gears and develop some power. The problem is less pronounced when the car is moving at speed than it is when it is just starting to move. Revving the engine when in park can get it to start behaving more normally (most of the time).
I've been searching around, but am a bit stumped. Anyone seen this before/ have any advice?
The most confounding thing about the whole problem is that it is intermittent, and half the time the car runs beautifully, so I'm reluctant to just take it to the shop, as an intermittent problem to me says that one specific thing is working or not working part of the time, and that sounds like something I can fix myself with a little help and advice.
Thanks in advance.
