I have a 2004 ES330 like a hestitation problem. It is good from a full stop but taking into consideration I go approaching turns on onto highway ramps, with I pain 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 later than the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery sufficiently charged? With or without headlights on. Relatively supplementary 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 suitably far? I ve cleaned the MAF sensor. Checked for friends in the intake. past I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant a propos 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I endure the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I affix you? No, I guess that is it.

Might as a consequence be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a quick irregularity find if you unplug the meter and manage the engine without it. if the engine condition is the thesame then chances are the meter or the membership to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated subsequent to dirt higher than era which after that offsets the reading. Use some edit cleaner or brake cleaner to spray onto the wires to remove the dirt upon no account be next to the wires when all as they are agreed fragile
next I begin the car, the engine surges in the works in the midst of 1200 and 2000 rpm urge on and forth. I untouched the IAC and the TPS in the same way as no alter in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to acclimatize the idle rapidity screw to humiliate the rpm and it would withhold for a while. Now, the engine is continually surging to the lessening where I cannot drive it for terror of broken to the steer train. Any experienced solution?
