I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full end but in the manner of I go on the subject of turns upon onto highway ramps, in the manner of I afflict 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 thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery thoroughly charged? With or without headlights on. Relatively other 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 connections in the intake. past 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 normal TPS. I give a positive response the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know back I connect you? No, I guess that is it.
Might in addition to be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick oddity find if you unplug the meter and run the engine without it. if the engine condition is the same after that chances are the meter or the membership to it is faulty. Its as a consequence worth cleaning the MAF sensor wires, as they can get coated once dirt higher than times which later offsets the reading. Use some contact cleaner or brake cleaner to spray can onto the wires to surgically remove the dirt upon no account be next to the wires next all as they are completely fragile
This could be a large vacuum leak ,with the MAF associated it is lonesome measuring the freshen that is getting taking into account the MAF, in view of that if the intake manifold is sucking in freshen the expose to fuel ratio will be no question out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. taking into consideration carb cleaner spray can spray can in the place of the hissing like the engine supervision and like you listen the engine stall or rev superior there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
