Wait, are you saying the RPM needle goes past 5-6,000 on the gauge?

Bad misfire as TechII mentioned, how old are the wires/ miles on spark plugs?
Would be good to know if there are any Obd2 stored codes present/history.

If I recall correctly, under bad misfire conditions, the computer will unlock the torque converter to get engine RPM'* increased to take the load off the engine.
Like already asked, how long since last full tune up?

I'll replace the plugs and the wires .
today I check the coils and all the 3 make "ticking" noise when I unconnected them .
just to be clear , the warning light came only in high RPM .
