It is always good to get two opinions on your needed service. Have another automotive repair service give you a diagnosis and estimate before you commit to anything. Then go to AZ Automasters. They do fine work at reasonable prices and will not let you down. The Managers insist that you are happy and will even ask you if anything needs to be changed. Be careful but be smart. I had a warning light and took it to them after being quoted a huge price to fix whatever it was. They removed the warning light and I went through emissions testing just fine. They are very professional,.
