What causes the Wuling Rongguang's idle speed to stay at 2000 RPM and not drop?
1 Answers
Wuling Rongguang's idle speed staying at 2000 RPM and not dropping can be caused by normal conditions or other reasons such as an oversized idle jet. Specific explanations are as follows: Normal phenomenon: High idle speed during cold starts is normal. The engine requires higher RPM to quickly reach optimal operating conditions and needs a richer air-fuel mixture, which increases air intake and fuel injection, resulting in higher RPM. Other reasons: Oversized idle jet; loose throttle shaft; poor performance in individual cylinders; intake manifold leaks due to improper fixation; brake vacuum booster air valve leaks or other vacuum pipe leaks; distributor contact gap too small; excessive carbon buildup, etc.
