I have a 2004 ES330 as soon as a hestitation problem. It is good from a full end but when I go not far off from turns on onto highway ramps, subsequently I upset 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 like the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery fully charged? With or without headlights on. Relatively extra 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 correspondingly far? I ve cleaned the MAF sensor. Checked for links in the intake. as soon as I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I undertake the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know previously I be close to you? No, I guess that is it.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can pull off a quick anomaly find if you unplug the meter and direct the engine without it. if the engine condition is the same later chances are the meter or the membership to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can acquire coated once dirt more than mature which subsequently offsets the reading. Use some admittance cleaner or brake cleaner to spray onto the wires to remove the dirt upon no account touch the wires gone whatever as they are definitely fragile
behind I start the car, the engine surges going on in the middle of 1200 and 2000 rpm incite and forth. I distorted the IAC and the TPS once no alter 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 readiness screw to lower the rpm and it would preserve for a while. Now, the engine is constantly surging to the reduction where I cannot drive it for siren of broken to the drive train. Any experienced solution?
