Hi all,
Hope somebody has an idea about the following symptom :
Recently my Bosch pump ha started to rev very high in idle.
Apart from that everything is normal, but if I stop say at a traffic light, the rev counter shows between 1200 to 1500 Rpm in idle. I tried the following :
Checking the throttle cable, if it maybe is stuck or something, but it's all looking normal.
When I move the throttle at the pump by hand, and kind of move it back into position very fast, the pump goes back to normal idle speed, sitting around 800rpm or so. As soon as I drive, the story starts again. I reversed into my driveway there earlier, idling around 1500 Rpm, opened the bonnet, moved the throttle back quickly by hand, and immediately the pump went back to normal idle speed. What I don't understand is the following :
When the pump revs high, the throttle lever is at exactly the same position, means it sits properly against the stop screw at the back, yet it revs higher then usual?
Could that problem be underneath the lever? Anyone had that problem before?
Every idea is much appreciated
I have not altered anything on the pump before this happened..
