Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
With the engine running can I take voltage readings on the connector for the idle air stabilizer? Can I check the Ohms for the Idle stabilezer and what should it be?
Attachments are only available to registered users.
The idle is approximately at 1800 rpm when in park. This high idle moves the car along at over 30 mph which makes it difficult to drive in the city and requires much braking.
I would really like information on testing voltages in the circuit such as wires to idle speed solenoid, power to idle control box and Ohms of the various components such as:
cooant temp sensor
oil temp sonsor
idle stabilizer solenoid
and anything else I could test in the circuit.
