I have a 2004 ES330 once a hestitation problem. It is fine from a full stop but subsequent to I go going on for turns on onto highway ramps, in imitation of I upset the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon later than the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery adequately charged? With or without headlights on. Relatively extra 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 hence far? I ve cleaned the MAF sensor. Checked for links in the intake. once I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant a propos 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know previously I be close to you? No, I guess that is it.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can do a fast deformity locate if you unplug the meter and rule the engine without it. if the engine condition is the thesame after that chances are the meter or the link to it is faulty. Its in addition to worth cleaning the MAF sensor wires, as they can acquire coated taking into consideration dirt greater than times which then offsets the reading. Use some right to use cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account be adjacent to the wires subsequent to anything as they are definitely fragile
