I have a 2004 ES330 in the same way as a hestitation problem. It is fine from a full stop but bearing in mind I go roughly speaking turns upon onto highway ramps, in the manner of 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 next the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights turn 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 so far? I ve cleaned the MAF sensor. Checked for friends in the intake. subsequently I put my Turbo OBDII app on, everything seems good except that the TPS stays constant nearly 30%. This is a drive-by-wire model for that reason it has not throttle cable or usual TPS. I believe the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know past I border 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. once I unplug it and control the motor, the car runs aggressive and at 850ish. I can on your own guess that my further 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 rule in the oscillate of rpm though? I think it lonesome adjusts it on 1k..
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is then an intermittent popping solid coming at idle.
