I have a 2004 ES330 as soon as a hestitation problem. It is good from a full stop but like I go on the order of turns on onto highway ramps, later I afflict 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 past the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery fully 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 in view of that far? I ve cleaned the MAF sensor. Checked for friends in the intake. in imitation of I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant approximately 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I give a positive response the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know previously I be close to you? No, I guess that is it.
Might along with be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick aberration locate if you unplug the meter and direct the engine without it. if the engine condition is the same next chances are the meter or the membership to it is faulty. Its with worth cleaning the MAF sensor wires, as they can get coated later dirt on top of times which then offsets the reading. Use some edit cleaner or brake cleaner to spray onto the wires to surgically remove the dirt upon no account be next to the wires with whatever as they are unconditionally fragile
afterward I begin the car, the engine surges happening in the company of 1200 and 2000 rpm back up and forth. I misrepresented the IAC and the TPS like no modify in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle quickness screw to lower the rpm and it would preserve for a while. Now, the engine is at all times surging to the narrowing where I cannot drive it for alarm bell of damage to the steer train. Any experienced solution?
