I have a 2004 ES330 afterward a hestitation problem. It is good from a full stop but in the same way as I go all but turns on onto highway ramps, in the same way as I upset the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in imitation of the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery thoroughly 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 thus far? I ve cleaned the MAF sensor. Checked for contacts in the intake. behind I put my Turbo OBDII app on, all seems fine except that the TPS stays constant not far off from 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I acknowledge the TPS is integrated when the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know before I be next to you? No, I guess that is it.
Might as well as be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a quick aberration locate if you unplug the meter and rule the engine without it. if the engine condition is the thesame later chances are the meter or the association to it is faulty. Its next worth cleaning the MAF sensor wires, as they can get coated similar to dirt more than grow old which after that offsets the reading. Use some retrieve cleaner or brake cleaner to spray can onto the wires to surgically remove the dirt on no account lie alongside the wires behind everything as they are extremely fragile
