I have a 2004 ES330 taking into consideration a hestitation problem. It is fine from a full stop but in the manner of I go nearly turns upon onto highway ramps, next I upset the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the same way as the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery abundantly charged? With or without headlights on. Relatively new 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. as soon as I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant around 30%. This is a drive-by-wire model correspondingly it has not throttle cable or usual TPS. I acknowledge the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously 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 expose flow meter and said it was good. in the manner of I unplug it and run the motor, the car runs aggressive and at 850ish. I can solitary 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 control in the substitute of rpm though? I think it lonely adjusts it concerning 1k..
