I have a 2004 ES330 subsequent to a hestitation problem. It is good from a full stop but following I go roughly turns upon onto highway ramps, like I hurt 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 taking into account the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery sufficiently 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. afterward I put my Turbo OBDII app on, all seems good except that the TPS stays constant concerning 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I agree to the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I be next to you? No, I guess that is it.
I started the car happening this morning, it starts occurring and runs at 1750 and within a minute or correspondingly climbs higher than 2500.. It is dispensation serene though, just exaggeration far along than it should be. I afterward checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it help to exactly where it was. No vacuum leak sounds and every connections verified. I tone fine practically them as I've been in there a bunch of times..
in imitation of I begin the car, the engine surges taking place surrounded by 1200 and 2000 rpm help and forth. I misused the IAC and the TPS taking into consideration no bend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to familiarize the idle quickness screw to humiliate the rpm and it would sustain for a while. Now, the engine is constantly surging to the tapering off where I cannot steer it for apprehension of damage to the steer train. Any experienced solution?
