What to Do When the Wuling B12 Idle Speed Is Too High and Won't Lower?
1 Answers
If the Wuling B12 idle speed is too high and won't lower, you can clean the throttle body and idle speed motor. If this doesn't resolve the issue, the idle speed motor may be internally stuck and require replacement. Below are some common causes related to idle speed fluctuations: 1. Dirt from the air and sludge from gasoline can easily clog the vehicle's throttle body, causing poor idle speed motor operation. 2. Excessive carbon buildup may lead to improper valve sealing, poor fuel injector atomization, and insufficient combustion. 3. A clogged exhaust pipe can result in poor exhaust flow. 4. Air leaks may cause insufficient vacuum pressure.
