I have a 2004 ES330 past a hestitation problem. It is good from a full end but subsequent to I go going on for turns upon onto highway ramps, later than I hurt 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 in imitation of the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights point on? Is the battery fully charged? With or without headlights on. Relatively additional 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 hence far? I ve cleaned the MAF sensor. Checked for links in the intake. when I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant as regards 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I take the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know before I attach you? No, I guess that is it.
Might next be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick defect find if you unplug the meter and govern the engine without it. if the engine condition is the thesame subsequently chances are the meter or the membership to it is faulty. Its also worth cleaning the MAF sensor wires, as they can get coated taking into account dirt more than times which subsequently offsets the reading. Use some entre cleaner or brake cleaner to vaporizer onto the wires to remove the dirt on no account be next to the wires past anything as they are utterly fragile
