hi there all

does anybody out there know how to turn up the idle on a 98 LC 105 diesel i cant find a screw or anything and i don't want to bugger things up i think the idle is a little to low its about 500rpm in neutral and want to turn it up about 100 rpm or so (oh its an auto too)
i would like a description or can somebody post a pic pointing to what i should do

regards brentos

Hi Brentos, best not to use the knob on the dash for base idle ajustment, if it is idling too slow there is an idle stop screw on the linkage on top of the injector pump. With the emgine stopped work the throttle by hand and watch how it turns the quandrant on the pump, you will see the ajustable stop that the arm rests against, it can be ajusted using a 10mm spanner on the locknut and a 8mm to turn the screw.
Regards Ken.

See these two adjustment screws.... I think it's the rear one for idle and the front one for the idle-up when the aircon is running.

Image Could Not Be Found

The one at the back of the injection pump has a non-tamper steel thread....not that one!



I adjusted mine with htese, no problems.

Good luck.
