timing...

Does anyone know the timing for 280E w123?


My car runs smooth, till i put the hammer down. When i give more gas, the car jerks almost if it doesn't get enough gas or something... Any ideas what it can be? I did recently replaced the spark plugs.

300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
Did it happen BEFORE YOU CHANGED THE PLUGS?

OR is this a new thing after the plugs?
Did you use the correct copper plug? that engine won't like platinum plugs.

I checked the plugs, I replaced it with WR8DC +. What is the wrong plugs. I've just ordered my new plugs. going to replace it tonight. the right plugs are W7bc.

I've done some research, and according to another mercedes forum website, the "r"(wr8dc+) stands for resistor. the car i'm driving already have a resistor installed. that is why it is not running smooth...
