Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello and welcome to just answer and allowing me to assist you. question/ HAVE YOU HAD THE EXHAUST CHECKED FOR LEAKS? The easy way to do that is to have someone hold a heavy towel tight on the exhaust to build up pressure while the car is running, then listen under neath the entire length of the vehicle for hissing or a forced air sound. Or take ito an exhaust p and have then it. That's what I would do first. hope this helps yr decision. I f you need further assistance I'll be happy to d so.
