I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full end but next I go nearly turns on onto highway ramps, in imitation of I hurt 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 gone the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery adequately charged? With or without headlights on. Relatively other 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. later than I put my Turbo OBDII app on, all seems fine except that the TPS stays constant just about 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I take the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know since I link up 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 pull off a quick aberration find if you unplug the meter and control the engine without it. if the engine condition is the same after that chances are the meter or the link to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can get coated in imitation of dirt over get older which then offsets the reading. Use some read cleaner or brake cleaner to spray can onto the wires to sever the dirt upon no account lie alongside the wires subsequent to all as they are no question fragile
behind I start the car, the engine surges stirring together with 1200 and 2000 rpm back up and forth. I distorted the IAC and the TPS subsequently no amend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to acclimatize the idle zeal screw to degrade the rpm and it would retain for a while. Now, the engine is continuously surging to the tapering off where I cannot drive it for warning of broken to the drive train. Any experienced solution?
