Hello, my name is***** you tell me if the noise only occurs when the oil light comes on?
Customer: replied 10 months ago.
Thx! The noise comes on consistently when applying throttle, independently of the low oil pressure warning.

Sorry for the delay in getting back with you. Would you still like some help with this?

thx
Expert:  FIXITMAN replied 10 months ago.

Thank you. I would change the engine oil and filter as a clogged or low quality oil filter can cause this. If that is fine then the oil control solenoid for the variable valve timing may be failing which will cause this noise to occur.

Thx, what would cause the buzzing w/ throttle?
