It is fine from a full stop but with I go going on for turns on onto highway ramps, in the manner of I depress the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon later than the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery adequately charged? With or without headlights on. Relatively other battery. 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 appropriately far? I ve cleaned the MAF sensor. Checked for associates in the intake. once I put my Turbo OBDII app on, anything seems good except that the TPS stays constant a propos 30%.
