Hi, i took the car for a drive today and without notice, it started doing a loud "TAC TAC" noise very loud, sound to me maybe like a valve??, and also felt that i had lost some power and the car will not idle anymore. The "TAC TAC" noise is not something that i could time, like for example every engine cycle, only when i press the throttle and louder when driving compare to parked.
I'll try to upload a video if i can.

Please any reflection are welcome and hope that one of you guys can guide me on what to check.

Thank you

Adrien
