Vehicle: 2008 IS250 AWD
My IS has had some engine noise for a few weeks now but I didnt think much of it at first since it was mainly at cold starts.
But it has been getting worse and worse making different noises till today there is was a MAJOR loss of power!!
Here is a video to what it sounds like
I keep reading about the issue being related to carbon buildup is that true?? because i don't want to pay the Lexus dealership an expensive diagnosis fee but I do need to fix this ASAP.
