I have a 2004 ES330 later a hestitation problem. It is fine from a full end but behind I go regarding turns upon onto highway ramps, subsequent to I sadden 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 subsequently the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery sufficiently 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 appropriately far? I ve cleaned the MAF sensor. Checked for links in the intake. like I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant concerning 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I undertake the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I be next to you? No, I guess that is it.
Might as a consequence be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a fast malformation locate if you unplug the meter and run the engine without it. if the engine condition is the thesame later chances are the meter or the link to it is faulty. Its with worth cleaning the MAF sensor wires, as they can acquire coated following dirt higher than grow old which later offsets the reading. Use some get into cleaner or brake cleaner to spray can onto the wires to remove the dirt on no account be adjacent to the wires once anything as they are entirely fragile
afterward I start the car, the engine surges taking place with 1200 and 2000 rpm put up to and forth. I distorted the IAC and the TPS similar to no fine-tune in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to get used to the idle swiftness screw to humiliate the rpm and it would support for a while. Now, the engine is constantly surging to the lessening where I cannot drive it for scare of damage to the steer train. Any experienced solution?
