Lexus problem, maybe

I have a 1997 Lexus Es300 while accelerating i hear a ringing noise under the front of the car. A great problem??

Maybe. It could be pinging, it could be a peripheral component breaking down, it could be a number of things. Some of them could end up as serious damage if unaddressed. I’d suggest having it looked at.

Sounds like the cat shield rattlinginginging. Big band clamp may help.
