I have a 2004 ES330 with a hestitation problem. It is fine from a full stop but considering I go on turns on onto highway ramps, in imitation of I distress the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon past the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery abundantly charged? With or without headlights on. Relatively new 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 in view of that far? I ve cleaned the MAF sensor. Checked for links in the intake. as soon as I put my Turbo OBDII app on, everything seems good except that the TPS stays constant going on for 30%. This is a drive-by-wire model fittingly it has not throttle cable or usual TPS. I admit the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know past 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 complete a fast irregularity find if you unplug the meter and direct the engine without it. if the engine condition is the similar later chances are the meter or the relationship to it is faulty. Its also worth cleaning the MAF sensor wires, as they can get coated past dirt beyond epoch which subsequently offsets the reading. Use some gate cleaner or brake cleaner to spray can onto the wires to cut off the dirt upon no account be adjacent to the wires once whatever as they are categorically fragile
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is as a consequence an intermittent popping sealed coming at idle.
