Why is the idle speed needle not moving?
1 Answers
The reasons for the idle speed needle not moving may include excessive engine carbon deposits or instrument failure. The specific causes and solutions are as follows: Excessive engine carbon deposits: When engine fuel does not burn completely, it easily forms carbon deposits. Excessive carbon deposits can lead to reduced engine power because the carbon deposits adhere to the spark plugs, diminishing their ignition capability and failing to generate sufficient power, causing the idle speed needle to stop moving. Solution: Clean the carbon deposits. Instrument failure: The fuse of the instrument panel may be blown, or the wiring may be loose or short-circuited, causing the idle speed needle to stop moving. Solution: Perform repairs.
