I have a 2004 ES330 in the same way as a hestitation problem. It is good from a full end but like I go in this area turns on onto highway ramps, past I depress the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon considering the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery adequately 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 fittingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. subsequently 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 correspondingly it has not throttle cable or usual TPS. I admit the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know in the past I attach you? No, I guess that is it.

I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. later I unplug it and govern the motor, the car runs harsh and at 850ish. I can on your own guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much run in the swap of rpm though? I think it lonely adjusts it in this area 1k..
Hello the TPS does have an effect on switching the car into idle mode fittingly I'd suggest to make distinct the throttle dish is 100% closed and not slightly beached subsequently carbon. and then become accustomed the TPS thus that the IDL fasten is continuous to the E2 fasten when the throttle is closed, and log on circuit similar to the throttle is just cracked. Don't bother nearly any voltages, the IDL door is the in point of fact important one.
