I have a 2004 ES330 once a hestitation problem. It is good from a full stop but in imitation of I go on the subject of turns on onto highway ramps, following I afflict the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon later than the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery sufficiently 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 hence far? I ve cleaned the MAF sensor. Checked for friends in the intake. next I put my Turbo OBDII app on, whatever seems fine 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 understand the TPS is integrated past the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know before I attach you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. past I unplug it and manage the motor, the car runs unfriendly and at 850ish. I can unaided 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 run in the substitute of rpm though? I think it and no-one else adjusts it with reference to 1k..
I don't have any check engine lights unless I unplug the MAF sensor. taking into account the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is then an intermittent popping hermetic coming at idle.
