Hello All,
Latest Update:
Well, I took it to Lexus Dealer for a diagnostic (charge: about $46.00) and they said the problem was the Air Flow Meter (code 31). They quoted me $1,290 parts and labor (labor rate: $85 per hour; Time: 1.5 hours). The part itself costs $1,100.
So I contacted the Salvage Yard that I talked to previously and they said they could order it for me (Cost: $125.00) and it would get here Monday or Tuesday. At that point, I guess I will take it somewhere (maybe back to Toyota Dealer) and have them put it on (Toyota will charge about $65.00 for labor).
Thanks to all your input. Feel free to leave additional comments or questions !!!
P.S. Is there any difference between "air flow sensor" and "air flow meter" ???
