I have a 2004 ES330 considering a hestitation problem. It is good from a full end but in the manner of I go as regards turns on onto highway ramps, next I distress 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 later the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery sufficiently 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 correspondingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. behind I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in relation to 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I acknowledge the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know past 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 let breathe flow meter and said it was good. as soon as I unplug it and rule the motor, the car runs argumentative and at 850ish. I can unaided guess that my supplementary 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 swing of rpm though? I think it solitary adjusts it something like 1k..
Hello the TPS does have an effect on switching the car into idle mode fittingly I'd recommend to make sure the throttle plate is 100% closed and not slightly ashore behind carbon. and later get used to the TPS for that reason that the IDL fasten is continuous to the E2 fix following the throttle is closed, and edit circuit with the throttle is just cracked. Don't distress practically any voltages, the IDL approach is the in fact important one.
