I have a 2004 ES330 taking into consideration a hestitation problem. It is good from a full end but when I go vis--vis 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 later the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery thoroughly 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 so far? I ve cleaned the MAF sensor. Checked for associates in the intake. past I put my Turbo OBDII app on, anything seems good except that the TPS stays constant approximately 30%. This is a drive-by-wire model as a result it has not throttle cable or normal TPS. I take the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know previously I connect 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 complete a quick deformity find if you unplug the meter and manage the engine without it. if the engine condition is the thesame next chances are the meter or the relationship to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can acquire coated behind dirt over times which then offsets the reading. Use some right of entry cleaner or brake cleaner to spray can onto the wires to remove the dirt upon no account be adjacent to the wires once everything as they are extremely fragile
