Engine dying when I accelerate slowly. 1979 280SE
OK, so I've had this car for a couple of months now. A week or two ago that it started doing this thing where it will die when I start accelerating too slowly. When the engine is revved up it works fine, no problem. It idles OK, perhaps a little rougher than I would like, and if I accelerate smoothly from a stop it has no problem, but when I accelerate too slowly, tap on the gas peddle lightly, or when I start to accelerate but then have to stop suddenly as often happens in city traffic the car dies, I have to quickly put it in park turn the key off and then on to restart it. No problems restarting it will fire right back up. It doesn't do this all the time, but I often notice the engine catching slightly when I press on the accelerator as it switches off of idle. It tends to start dying more when the engine has been running for a while.
To give you a couple of pieces of background on this to see if it gives you any ideas. It was running great when I first got it, but I had to take it in for a bit of work. Breaks and replacement of a radiator hose. This happened several weeks before it starting behaving like this. Also, when I first got it I wasn't aware that Mercedes require Premium gas so I ran one tank of regular through the engine, but I have run two tanks of Premium through it since then. I don't think this would cause this problem but thought it be good to mention this.
I think the timing may be off, my last classic car was a dodge dart and I checked the timing on it regularly, but the timing light I had for it was stolen along with the car last year, so I'm wondering if checking the timing is fairly easy on a Mercedes, and if anyone can walk me through it. If it uses a timing light like with the dart it should be fairly easy, I just need to know which belt to shine it at as adjusting the distributor cap seems fairly easy.
