I have a 2004 ES330 when a hestitation problem. It is fine from a full end but subsequent to I go just about turns upon onto highway ramps, when 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 afterward the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery thoroughly charged? With or without headlights on. Relatively extra 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 fittingly far? I ve cleaned the MAF sensor. Checked for links in the intake. later I put my Turbo OBDII app on, anything seems good except that the TPS stays constant not far off from 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I put up with the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know before I link up you? No, I guess that is it.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick malformation locate if you unplug the meter and rule the engine without it. if the engine condition is the thesame next chances are the meter or the attachment to it is faulty. Its next worth cleaning the MAF sensor wires, as they can get coated later dirt on top of mature which subsequently offsets the reading. Use some log on cleaner or brake cleaner to vaporizer onto the wires to separate the dirt on no account touch the wires taking into account whatever as they are unquestionably fragile
