Mechanic s Assistant: What is the model of your 04 Lexus? ES330 Mechanic s Assistant: Are you fixing your vehicle yourself? What have you tried correspondingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. like I put my Turbo OBDII app on, anything seems good except that the TPS stays constant around 30%.
