I have a 2004 ES330 in the same way as a hestitation problem. It is good from a full stop but later than I go not far off from turns upon onto highway ramps, when 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 later than the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery adequately charged? With or without headlights on. Relatively new 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. similar to I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant with reference to 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I take on the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know since I affix 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 pull off a quick malfunction find if you unplug the meter and direct the engine without it. if the engine condition is the thesame after that chances are the meter or the link to it is faulty. Its then worth cleaning the MAF sensor wires, as they can get coated taking into account dirt higher than grow old which next offsets the reading. Use some admittance cleaner or brake cleaner to spray onto the wires to surgically remove the dirt upon no account touch the wires when all as they are extremely fragile
