I have a 99 Lexus GS300 with 125,000 miles. Cost of VVR replace?

I tried that first but couldn't match up to anything. Thanks.

Are there other parts that should also be replaced when this is being done? I don't want to have to do another repair 2 months down the road. Thank you for responding.

You are welcome. Without seeing the car I have no way of knowing. But, I would suggest bringing it in for us to see anyways.
