I have a 2004 ES330 subsequent to a hestitation problem. It is good from a full stop but behind I go re turns on onto highway ramps, later I pain the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon similar to the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery thoroughly charged? With or without headlights on. Relatively additional 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. gone I put my Turbo OBDII app on, anything seems good except that the TPS stays constant approaching 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I say yes the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I connect you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. once I unplug it and run the motor, the car runs gruff and at 850ish. I can lonely guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much control in the alternative of rpm though? I think it lonely adjusts it on 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you up to date upon every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms happening and is warmed up? oftentimes in engine comport yourself many factors may cause the thesame symptom(s)
