We own 2001 Lexus RS300. The Engine light was on and needed inspections. I was told It needs two Air flow sensor. that was not it! I was even told it needs two Oxygen sensor!. these parts are very expensive. I took the Car to the shop. Tommy Welch called and said "there are have several air leaks a couple of gaskets that need to be changed. Tommy & Ken fixed the car. the issue is you don't know if it is fixed until you drive the car about 60 miles. I drove the car for 3 days light did not come back, i went back to them and got the inspection. I strongly recommend Innovative auto works. They are good and you can trust them.
