Hi, I've been spending a lot of time with my 300SDL and I think my 92 300D got jealous and began claiming attention
.
The thing is that from one day to another I totally lost acceleration. My first thought was that the kickdown switch went bad but now I don't know. Below are the symptoms and the troubleshooting I did:
Symptoms:
Smooth upshifting (all gears) until I get to 2200 RPMs and from there on the engine does not want to go above that. It stays there and that it is. It is like reaching a limiter at those RPMs. On park, the RPMs go above the 2200 without a problem.
Troubleshooting done:
1. I checked the voltage coming from the switch below the accelerator pedal to the manifold micro switch (P/N 002 545 23 14) by the throttle and I got juice ON and OFF as it is supposed to work when hitting the pedal to the metal.
2. I bridged the wires coming to the throttle micro switch and it did not change anything.
I will replace the micro switch but I am afraid that I might be missing something else. Any thoughts?
Thanks!
