Roewe 550 is unstable when driving.

Hello: Regarding your question, if this fault still occurs after cleaning the throttle body, it may be the clutch switch. You can try to change a new clutch switch. Secondly, you can check it yourself first. When the vehicle is driving, such as 5th or 4th gear, you can select the gear without stepping on the clutch, or you can try to select the gear only by stepping on 1/3 stroke. If the idle speed is not at this time, there are some problems with the clutch, but this problem will not affect the normal use of the vehicle and does not require maintenance and replacement. You can use it safely.
