I have a 2004 ES330 subsequently a hestitation problem. It is fine from a full stop but once I go roughly speaking turns on onto highway ramps, considering 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 taking into consideration the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position 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 thus far? I ve cleaned the MAF sensor. Checked for connections in the intake. past I put my Turbo OBDII app on, everything seems good except that the TPS stays constant with reference to 30%. This is a drive-by-wire model fittingly it has not throttle cable or usual TPS. I believe the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know before I attach you? No, I guess that is it.
Might along with be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a fast anomaly find if you unplug the meter and govern the engine without it. if the engine condition is the similar subsequently chances are the meter or the relationship to it is faulty. Its as a consequence worth cleaning the MAF sensor wires, as they can acquire coated in imitation of dirt higher than times which later offsets the reading. Use some retrieve cleaner or brake cleaner to spray onto the wires to separate the dirt on no account adjoin the wires in the manner of everything as they are certainly fragile
