I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full stop but later I go a propos turns on onto highway ramps, similar to I hurt the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon gone the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery abundantly 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 in view of that far? I ve cleaned the MAF sensor. Checked for associates in the intake. following I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant all but 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I tolerate the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know since I be close to 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. once I unplug it and manage the motor, the car runs sharp and at 850ish. I can unaccompanied guess that my extra 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 rule in the vary of rpm though? I think it by yourself adjusts it approaching 1k..
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is then an intermittent popping unquestionable coming at idle.
