I have a 2004 ES330 behind a hestitation problem. It is good from a full stop but in the manner of I go on turns upon onto highway ramps, in imitation of I depress 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 similar to the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery sufficiently 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 for that reason far? I ve cleaned the MAF sensor. Checked for contacts in the intake. taking into account I put my Turbo OBDII app on, anything seems good except that the TPS stays constant regarding 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I agree to the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know in the past I affix you? No, I guess that is it.

Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick irregularity locate if you unplug the meter and manage the engine without it. if the engine condition is the thesame after that chances are the meter or the attachment to it is faulty. Its moreover worth cleaning the MAF sensor wires, as they can acquire coated considering dirt greater than period which later offsets the reading. Use some entrance cleaner or brake cleaner to spray can onto the wires to surgically remove the dirt upon no account touch the wires past everything as they are certainly fragile
Hello the TPS does have an effect on switching the car into idle mode appropriately I'd suggest to create clear the throttle plate is 100% closed and not slightly grounded subsequently carbon. and after that adapt the TPS therefore that the IDL fix is continuous to the E2 pin in the same way as the throttle is closed, and right of entry circuit later the throttle is just cracked. Don't make miserable very nearly any voltages, the IDL retrieve is the in reality important one.
