I have a 2004 ES330 gone a hestitation problem. It is good from a full end but when I go on the subject of turns upon onto highway ramps, later than 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 like the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery abundantly charged? With or without headlights on. Relatively other 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 suitably far? I ve cleaned the MAF sensor. Checked for contacts in the intake. as soon as I put my Turbo OBDII app on, anything seems good except that the TPS stays constant with reference to 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know back 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 freshen flow meter and said it was good. next I unplug it and direct the motor, the car runs gruff and at 850ish. I can lonesome guess that my additional 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 govern in the substitute of rpm though? I think it only adjusts it more or less 1k..
Hello the TPS does have an effect on switching the car into idle mode consequently I'd recommend to create distinct the throttle plate is 100% closed and not slightly ashore taking into account carbon. and later acclimatize the TPS thus that the IDL fasten is continuous to the E2 pin gone the throttle is closed, and get into circuit considering the throttle is just cracked. Don't make miserable practically any voltages, the IDL retrieve is the essentially important one.
