I have a 2004 ES330 once a hestitation problem. It is fine from a full stop but next I go nearly turns upon onto highway ramps, behind I depress 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 in the manner of the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery sufficiently charged? With or without headlights on. Relatively additional 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, everything seems fine except that the TPS stays constant with reference to 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I say you will the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: anything 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 expose flow meter and said it was good. once I unplug it and rule the motor, the car runs scratchy and at 850ish. I can without help guess that my new 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 rule in the alternating of rpm though? I think it on your own adjusts it roughly 1k..
I don't have any check engine lights unless I unplug the MAF sensor. in imitation of the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is in addition to an intermittent popping solid coming at idle.
