Any Sifu out there can help?
I just bought a waja with mivec auto ck4a...
If I drive normal without ram no problem with the gearshift.
However, when I ram the engine up to 5000 rpm some times the engine facing gear shift problem, but when I release the oil pedal a bit gear can shift..
Any Sifu know what is going on...?..
Is it sensor problem? Gear Box problem or maybe ecu problem?
Forgot to tell the previous owner only install the engine without the dashboard.. wiring problem cause the ecu reading conffius?
