I have a 2004 ES330 later than a hestitation problem. It is good from a full end but as soon as I go on the order of turns upon onto highway ramps, in imitation of I pain the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon gone the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery abundantly 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 fittingly far? I ve cleaned the MAF sensor. Checked for links in the intake. once I put my Turbo OBDII app on, anything seems good except that the TPS stays constant going on for 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I put up with the TPS is integrated behind the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know since I link up you? No, I guess that is it.
Might after that be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can do a fast idiosyncrasy find if you unplug the meter and rule the engine without it. if the engine condition is the same later chances are the meter or the attachment to it is faulty. Its moreover worth cleaning the MAF sensor wires, as they can get coated in the same way as dirt on top of period which after that offsets the reading. Use some gain access to cleaner or brake cleaner to vaporizer onto the wires to sever the dirt upon no account lie alongside the wires following all as they are utterly fragile
