Help with Mercedes motor rotation speed

[davizo70]

Helo,
I am an automative service technician. Today A 1994 MB was brought tom me, which had very high rotation speed (apprx. 3000). I cleaned the throttle, made adaptation using KTS, but got the rotation speed equal 4000... What can I do? In addition to this the car wirings are almost burned, sometimes they are toughching together... May be this is the reason? but the speed went up after my attempt to recover it. Please help.

Hi

I would advice you to sort the wiring problem first before any thing else.

For that you will need a good wiring diagram so that you don't damage the Engine ECU Unit.

Hope this helps.
