Low frequency vibration that makes me feel sick!
Hi Scotty. Thanks for doing what you do. My family loves your channel.
2001 Lexus RX300 auto AWD with about 200k miles. About 5 months ago it started producing a low frequency vibration at idle that reverberates your ear drums. It’s worse in drive or reverse, but still there in park and neutral. So seems to be worse at lower RPMs. It’s bad enough to shake the dash. I literally haven’t been able to drive it for months because it gives me a headache and makes me dizzy after about 5 minutes.
I’m a decent garage mechanic and replaced spark plugs, an o2 sensor that was giving a code, valve cover gaskets, PCV, and two engine mounts all with OEM parts, and cleaned out the IACV and intake ports. Nothing changed with the vibration. I then thought it was coming from the exhaust, but I had two exhaust shops look at it and they can’t find any issues. Fixed a few small exhaust leaks as well. Currently no codes
What could possibly be causing this vibration at idle? I’m too poor to upgrade the vehicle. I just want to figure out the vibration and fix it. It’s a great vehicle otherwise.
