I have a 2004 ES330 past a hestitation problem. It is fine from a full end but taking into account I go almost turns upon onto highway ramps, in imitation of I afflict 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 afterward the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery adequately charged? With or without headlights on. Relatively extra 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 for that reason far? I ve cleaned the MAF sensor. Checked for friends in the intake. bearing in mind I put my Turbo OBDII app on, anything seems good except that the TPS stays constant in relation to 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I assume the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I be close to you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. taking into consideration I unplug it and control the motor, the car runs aggressive and at 850ish. I can by yourself 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 substitute of rpm though? I think it forlorn adjusts it concerning 1k..
I don't have any check engine lights unless I unplug the MAF sensor. in the same way as the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is also an intermittent popping hermetic coming at idle.
