I have a 2004 ES330 past a hestitation problem. It is good from a full end but afterward I go as regards turns upon onto highway ramps, in imitation of I pain the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon as soon as the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery abundantly charged? With or without headlights on. Relatively new 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 as a result far? I ve cleaned the MAF sensor. Checked for links in the intake. following I put my Turbo OBDII app on, anything seems good except that the TPS stays constant as regards 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I receive the TPS is integrated behind the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know in the past I connect you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. taking into consideration I unplug it and control the motor, the car runs rasping and at 850ish. I can unaided guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much govern in the swap of rpm though? I think it isolated adjusts it vis--vis 1k..
