I have a 2004 ES330 in the manner of a hestitation problem. It is good from a full stop but similar to I go on the subject of turns upon onto highway ramps, subsequent to I afflict the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon once the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery sufficiently 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 consequently far? I ve cleaned the MAF sensor. Checked for connections in the intake. with I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in the region of 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I allow the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know past I affix you? No, I guess that is it.
Might furthermore be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick malformation find if you unplug the meter and govern the engine without it. if the engine condition is the similar after that chances are the meter or the link to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can get coated similar to dirt over period which then offsets the reading. Use some edit cleaner or brake cleaner to vaporizer onto the wires to separate the dirt upon no account touch the wires subsequently whatever as they are entirely fragile
