I just acquired a 1994 E280/S124 (T model) (124.088) estate (automatic) and, although it seems to run fine, the acceleration is very strange: I have to press the accelerator down quite a bit before getting any response, and then, when I do, it just takes off. I thought maybe it was a trans problem, but it does the same in neutral and park. The accelerator pedal and cable are also OK. Could it be the injectors that are clogged, and if so, do I need to take them out to clean or can I just try to add some cleaning product to the petrol? Any insight will be greatly appreciated.

Does it have ASR? That sounds like how my 129 behaves when ASR has failed.

Look at the throttle body - if it has a thick electrical loom coming from it it may well have ASR.

Thanks for the reply, but no, mine does not have ASR. It was a systems option which the original owner recognized as tending to be problematic so opted not to have it.

Look down the throttle body and watch the throttle butterfly as you pull the cable. The throttle plate should move proportionally to any cable pull.
