A Sentra N16 came into our workshop today. After road test + diagnostics, we found the REAL cause:
👉 The Timing Tensioner was fully maxed out — timing chain completely loose.
This causes RPM jumping, jerking, vibration and unstable acceleration.
We replaced the full timing set + new tensioner, did proper adjustment,
and the car returned to smooth acceleration with stable RPM.
If your N16 has:
⚠️ Unstable RPM
⚠️ Jerking during acceleration
⚠️ Sensors replaced but problem still same
It may be a timing chain issue.

🔧 Nissan Sentra N16：RPM乱跳的真正原因找到！
今天进厂的一台 Sentra N16
我们路试 + 诊断后，发现真正原因是：
👉 Timing Tensioner 已经伸到尽头，Timing Chain 完全松掉。
这会造成 RPM 跳动、加速顿挫、抖动、油门不稳定。
我们更换整套 Timing Set + 新 Tensioner，重新调整后，
车子恢复顺顺，加速稳定、RPM 不再乱跳。
如果你的 N16 出现：
⚠️ RPM 不稳
⚠️ 加速会顿
⚠️ 换 Sensor 也没改善
很大可能就是 Timing Chain 问题。
