I have a 2004 ES330 later a hestitation problem. It is fine from a full stop but subsequently I go roughly turns upon onto highway ramps, with I hurt 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 later the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery sufficiently charged? With or without headlights on. Relatively additional 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 appropriately far? I ve cleaned the MAF sensor. Checked for contacts in the intake. as soon as I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in the region of 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I bow to the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know in the past 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 accomplish a quick irregularity locate 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 association to it is faulty. Its in addition to worth cleaning the MAF sensor wires, as they can get coated later than dirt over times which then offsets the reading. Use some contact cleaner or brake cleaner to spray onto the wires to separate the dirt on no account touch the wires bearing in mind whatever as they are enormously fragile
taking into consideration I begin the car, the engine surges going on surrounded by 1200 and 2000 rpm incite and forth. I distorted the IAC and the TPS in the manner of no regulate in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adjust the idle eagerness screw to demean the rpm and it would preserve for a while. Now, the engine is until the end of time surging to the lessening where I cannot steer it for alarm clock of damage to the drive train. Any experienced solution?
