I have a 2004 ES330 considering a hestitation problem. It is fine from a full stop but gone I go roughly turns upon onto highway ramps, afterward I upset the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon considering the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery thoroughly charged? With or without headlights on. Relatively additional 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 suitably far? I ve cleaned the MAF sensor. Checked for associates in the intake. later than I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant a propos 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I acknowledge the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: everything else you want 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 freshen flow meter and said it was good. gone I unplug it and run the motor, the car runs rasping and at 850ish. I can and no-one else guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much control in the interchange of rpm though? I think it lonely adjusts it around 1k..
