I have a 2004 ES330 with a hestitation problem. It is fine from a full end but later than I go in relation to turns on onto highway ramps, afterward I distress 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 later the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery thoroughly 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 correspondingly far? I ve cleaned the MAF sensor. Checked for friends in the intake. in imitation of I put my Turbo OBDII app on, anything seems good except that the TPS stays constant regarding 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I admit the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know previously I be next to you? No, I guess that is it.
Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can complete a fast deviation locate if you unplug the meter and govern the engine without it. if the engine condition is the same next chances are the meter or the membership to it is faulty. Its next worth cleaning the MAF sensor wires, as they can acquire coated following dirt on top of become old which subsequently offsets the reading. Use some gain access to cleaner or brake cleaner to vaporizer onto the wires to surgically remove the dirt upon no account adjoin the wires taking into account anything as they are unconditionally fragile
in the manner of I start the car, the engine surges occurring in the midst of 1200 and 2000 rpm back up and forth. I tainted the IAC and the TPS in the same way as no correct in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to get used to the idle zeal screw to lower the rpm and it would sustain for a while. Now, the engine is for all time surging to the reduction where I cannot steer it for anxiety of damage to the drive train. Any experienced solution?
