Disappointed. Check engine light came on and a friend recommended Master Muffler in Provo. On his recommendation I brought my car to them. after looking over the car, they assured me that I needed a new EGR valve and a new distributor, and that would solve my problem. $800 dollars later, new EGR valve and new distributor, the check engine light came back on, throwing the exact same codes. I brought it back in to them expecting maybe that they would look at it again for free (considering that I had just paid them everything I had). But no, without any sign of empathy they proceeded to take another look at my car. Then charged me another $80 dollars to adjust my valves, which was also unsuccessful. Now I'm almost $900 dollars poorer and my car still hasn't been fixed. Needless to say, I will NEVER go back, and I will tell everybody I know to steer clear of Master Muffler.
