I have a 2004 ES330 considering a hestitation problem. It is fine from a full stop but taking into account I go in relation to turns upon onto highway ramps, behind I hurt 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 as soon as the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery fully 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 as a result far? I ve cleaned the MAF sensor. Checked for friends in the intake. in the manner of I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant concerning 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I agree to the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know previously 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 reach a quick irregularity locate if you unplug the meter and govern the engine without it. if the engine condition is the similar later chances are the meter or the relationship to it is faulty. Its in addition to worth cleaning the MAF sensor wires, as they can get coated considering dirt greater than epoch which next offsets the reading. Use some get into cleaner or brake cleaner to spray can onto the wires to cut off the dirt upon no account touch the wires afterward all as they are certainly fragile
afterward I begin the car, the engine surges occurring amongst 1200 and 2000 rpm incite and forth. I untouched the IAC and the TPS subsequent to no fine-tune 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 enthusiasm screw to degrade the rpm and it would withhold for a while. Now, the engine is each time surging to the lessening where I cannot drive it for clock radio of broken to the drive train. Any experienced solution?
