I have a 2004 ES330 later a hestitation problem. It is good from a full end but in imitation of I go just about turns on onto highway ramps, bearing in mind I upset 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 once the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery adequately 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 fittingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. later I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant going on for 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I recognize the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know before I attach you? No, I guess that is it.
Might then be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a fast irregularity locate if you unplug the meter and manage the engine without it. if the engine condition is the similar then chances are the meter or the relationship to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can get coated once dirt on top of epoch which next offsets the reading. Use some approach cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt upon no account be adjacent to the wires behind anything as they are categorically fragile
I don't have any check engine lights unless I unplug the MAF sensor. taking into consideration the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is in addition to an intermittent popping sound coming at idle.
