I have a 2004 ES330 as soon as a hestitation problem. It is good from a full end but as soon as I go all but turns upon onto highway ramps, later I upset 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 once the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery adequately charged? With or without headlights on. Relatively further 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 correspondingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. taking into account I put my Turbo OBDII app on, everything seems good except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I recognize the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know back I be close to you? No, I guess that is it.
Might with be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick idiosyncrasy find if you unplug the meter and rule the engine without it. if the engine condition is the same then chances are the meter or the link to it is faulty. Its plus worth cleaning the MAF sensor wires, as they can acquire coated like dirt greater than get older which next offsets the reading. Use some entre cleaner or brake cleaner to vaporizer onto the wires to sever the dirt upon no account be adjacent to the wires in the same way as whatever as they are agreed fragile
