I have a 2004 ES330 taking into account a hestitation problem. It is good from a full end but when I go something like turns on onto highway ramps, taking into consideration I sadden 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 similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery thoroughly 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 friends in the intake. later I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant more or less 30%. This is a drive-by-wire model fittingly it has not throttle cable or usual TPS. I say yes the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know since I connect 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. gone I unplug it and direct the motor, the car runs severe 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 control in the substitute of rpm though? I think it only adjusts it vis--vis 1k..
