Why now when I start my 98 Es300 with 82000 miles the engine sometimes make this squealing chirping bird like noise if you rev it a few times it stops and I noticed it occurs only sometimes after you park the car say while you are at work. Does anyone have any ideas? Oil change was done at a certified lexus dealer only 500 miles ago.
Any ideas? It seems to do it when the engine is cold and just started after it has been at rest for a while.
