I have a 2004 ES330 later than a hestitation problem. It is good from a full end but considering I go in relation to turns upon onto highway ramps, like 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 later the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery sufficiently 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 in view of that far? I ve cleaned the MAF sensor. Checked for contacts in the intake. bearing in mind I put my Turbo OBDII app on, anything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I undertake the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know since I attach you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. when I unplug it and run the motor, the car runs argumentative and at 850ish. I can unaided guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much direct in the alternative of rpm though? I think it only adjusts it in the region of 1k..
when I start the car, the engine surges going on between 1200 and 2000 rpm help and forth. I changed the IAC and the TPS in the manner of no modify in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adapt the idle promptness screw to demean the rpm and it would retain for a while. Now, the engine is forever surging to the dwindling where I cannot drive it for terrify of damage to the drive train. Any experienced solution?
