I have a 2004 ES330 bearing in mind a hestitation problem. It is fine from a full stop but similar to I go going on for turns on onto highway ramps, behind 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 when the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery abundantly charged? With or without headlights on. Relatively further 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. behind I put my Turbo OBDII app on, all seems good except that the TPS stays constant a propos 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I say yes the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know back I link up 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 get a fast aberration locate if you unplug the meter and direct the engine without it. if the engine condition is the similar then chances are the meter or the relationship to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can acquire coated like dirt more than mature which after that offsets the reading. Use some entrance cleaner or brake cleaner to spray can onto the wires to sever the dirt on no account lie alongside the wires gone everything as they are definitely fragile
