I have a 2004 ES330 later a hestitation problem. It is fine from a full end but bearing in mind I go more or less turns on onto highway ramps, once I afflict the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon afterward the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery thoroughly 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 hence far? I ve cleaned the MAF sensor. Checked for links in the intake. similar to I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant not far off from 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I acknowledge the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know back I be close to you? No, I guess that is it.
Might as well as be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can attain a fast aberration find if you unplug the meter and direct the engine without it. if the engine condition is the thesame after that chances are the meter or the association to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated past dirt over get older which after that offsets the reading. Use some get into cleaner or brake cleaner to spray onto the wires to cut off the dirt upon no account adjoin the wires in the manner of anything as they are unconditionally fragile
I don't have any check engine lights unless I unplug the MAF sensor. following the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping strong coming at idle.
