Hello,
I bought a kymco 400i 2019 with 50,000KM on it.
I am having the following problems if you can guide me i would appreciate it.
* sometime it turn off after 2 seconds of letting the throttle off.
* on traffic lights when i start accelerating sometime it turns off.
* high vibrations at low RPM and also when idleing.
* Check engine light ON
* Poor acceleration.
* hasitation when i start accelerating,
What's i did so far:
* replaced Spark plugs
* replaced the Belt and the clutch assemly
* cleaned the injection
* cleaned the throttle body
OBD check showed throttle body sensor mulfunction.
i feel that this is more of an AIR issue
Should i replace the Throttle body sensor or it's not connected to the symptoms i am having.
Thank you in advance
Appreciate any help.

@fullt1wst welcome here,
* high vibrations at low RPM and also when idleing.
..most probably not related to other issues...
since I had lately a similar issue it might be worth to check your fuel supply.
-measure the fuelpumps pressure with a simple manometer or somewhere in a shop.
Needs appr. 3 bar to function properly within our injection system.
-do a TPS reset
-do failure code reset (ignore #3 or do it with an diagtool)
Maybe att link gives you some support.
