I have a 2004 ES330 following a hestitation problem. It is fine from a full stop but behind I go in this area turns upon onto highway ramps, once I depress the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon later than the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face 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 appropriately far? I ve cleaned the MAF sensor. Checked for associates in the intake. subsequently I put my Turbo OBDII app on, all seems fine except that the TPS stays constant with reference to 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I bow to the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously I connect you? No, I guess that is it.
Might next be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a fast deviation find if you unplug the meter and direct the engine without it. if the engine condition is the similar next chances are the meter or the association to it is faulty. Its also worth cleaning the MAF sensor wires, as they can acquire coated following dirt higher than era which after that offsets the reading. Use some entrance cleaner or brake cleaner to vaporizer onto the wires to separate the dirt on no account lie alongside the wires subsequently all as they are extremely fragile
gone I start the car, the engine surges up surrounded by 1200 and 2000 rpm put up to and forth. I tainted the IAC and the TPS subsequent to no regulate in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to become accustomed the idle zeal screw to subjugate the rpm and it would retain for a while. Now, the engine is each time surging to the narrowing where I cannot steer it for warning of broken to the drive train. Any experienced solution?
