I have a 2004 ES330 subsequently a hestitation problem. It is good from a full end but afterward I go on the order of turns upon onto highway ramps, with I pain the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery adequately charged? With or without headlights on. Relatively extra 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 links in the intake. next I put my Turbo OBDII app on, everything 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 acknowledge the TPS is integrated similar to the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know past I link up you? No, I guess that is it.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast deviation locate if you unplug the meter and rule the engine without it. if the engine condition is the thesame next chances are the meter or the link to it is faulty. Its moreover worth cleaning the MAF sensor wires, as they can acquire coated later than dirt on top of get older which after that offsets the reading. Use some admittance cleaner or brake cleaner to spray can onto the wires to separate the dirt upon no account adjoin the wires in the same way as everything as they are unconditionally fragile
as soon as I begin the car, the engine surges taking place amongst 1200 and 2000 rpm urge on and forth. I tainted the IAC and the TPS considering no alter in symptoms. I have noticed that several Lexus SC’s have this thesame issue. Prior to this I would have to accustom yourself the idle speed screw to degrade the rpm and it would support for a while. Now, the engine is until the end of time surging to the point where I cannot steer it for alarm bell of damage to the steer train. Any experienced solution?
