The Millenia Is Much Quieter Now
The reason for the title, is that my 2001 Millenia just recently got a new EGR valve put in because the old one was a refurbished unit that the seller had claimed was brand new. Apparently, something failed in the EGR that was in the car and it wasn't working correctly. Hiley Mazda of Hurst fixed that problem with a new EGR valve, and a new piece of vacuum hose that apparently was split, according to them. It runs so much better now and I'm loving it more and more by the day!
