87 560 SL rough running
Hi All...
Now that we have replaced (all but the engine) fuel distributor, vacuum lines, plugs, wires, injectors,,,,,,more, and the rough running is still present, - a new source of this problem has surfaced. Will this fix it? The Air Mass Meter - $$$$ seems to have a voltage (dead spot) when depressing the accelerator, which, I am told could be causing the "problem". If I do replace this AMM, what could be next? Anyone have had a problem with this? What can I expect next? Anyone has a line on a used AMM Bosch part # 0438 121 037? Help! and thanks. JD |

AMM
is really a rare failure. I would double check everything else first. Note the similar issue on a similar car in this forum.

JD,
Which plugs(brand+p/n) and which plug wires(brand+p/n) In many cases (including my own!) this combination was the root of the problem. Bob
