I have a 2004 ES330 past a hestitation problem. It is good from a full end but gone I go a propos turns upon onto highway ramps, in imitation of I hurt the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in imitation 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 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 consequently far? I ve cleaned the MAF sensor. Checked for friends in the intake. afterward I put my Turbo OBDII app on, all seems fine except that the TPS stays constant as regards 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I put up with the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know in the past I connect 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. when I unplug it and govern the motor, the car runs aggressive and at 850ish. I can by yourself guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much run in the every second of rpm though? I think it without help adjusts it nearly 1k..
I don't have any check engine lights unless I unplug the MAF sensor. as soon as the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping unassailable coming at idle.
