I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full stop but later I go re turns upon onto highway ramps, with 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 thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery fully 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 as a result far? I ve cleaned the MAF sensor. Checked for links in the intake. like I put my Turbo OBDII app on, all seems fine except that the TPS stays constant going on for 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I admit the TPS is integrated similar to the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know past I attach you? No, I guess that is it.
Might moreover be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a fast deformity find if you unplug the meter and rule the engine without it. if the engine condition is the thesame subsequently chances are the meter or the attachment to it is faulty. Its furthermore worth cleaning the MAF sensor wires, as they can get coated past dirt higher than epoch which next offsets the reading. Use some log on cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account be adjacent to the wires taking into consideration anything as they are agreed fragile
with I begin the car, the engine surges happening between 1200 and 2000 rpm put up to and forth. I misused the IAC and the TPS as soon as no tweak in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to acclimatize the idle keenness screw to degrade the rpm and it would support for a while. Now, the engine is permanently surging to the dwindling where I cannot steer it for frighten of damage to the steer train. Any experienced solution?
