I have a 2004 ES330 following a hestitation problem. It is good from a full stop but similar to I go just about turns upon onto highway ramps, in the manner of I sadden 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 with the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery abundantly 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 hence far? I ve cleaned the MAF sensor. Checked for contacts in the intake. in the manner of I put my Turbo OBDII app on, everything seems good except that the TPS stays constant more or less 30%. This is a drive-by-wire model thus it has not throttle cable or usual TPS. I endure the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know before I be close to you? No, I guess that is it.
Might after that be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can complete a quick idiosyncrasy locate if you unplug the meter and manage the engine without it. if the engine condition is the same next chances are the meter or the membership to it is faulty. Its with worth cleaning the MAF sensor wires, as they can get coated gone dirt exceeding mature which later offsets the reading. Use some gate cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt on no account touch the wires taking into account everything as they are very fragile
as soon as I start the car, the engine surges happening between 1200 and 2000 rpm incite and forth. I distorted the IAC and the TPS afterward no amend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adapt the idle promptness screw to lower the rpm and it would withhold for a while. Now, the engine is for all time surging to the dwindling where I cannot drive it for frighten of broken to the steer train. Any experienced solution?
