I have a 2004 ES330 gone a hestitation problem. It is good from a full stop but in the same way as I go a propos turns upon onto highway ramps, gone I pain 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 when the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery adequately 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 fittingly far? I ve cleaned the MAF sensor. Checked for connections in the intake. bearing in mind I put my Turbo OBDII app on, all seems good except that the TPS stays constant more or less 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I allow the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know back 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. following I unplug it and rule the motor, the car runs aggressive and at 850ish. I can without help guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much control in the different of rpm though? I think it abandoned adjusts it on 1k..
I don't have any check engine lights unless I unplug the MAF sensor. bearing in mind the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is furthermore an intermittent popping hermetically sealed coming at idle.
