I have a 2004 ES330 subsequent to a hestitation problem. It is good from a full end but afterward I go concerning turns on onto highway ramps, later than I depress the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery sufficiently 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 hence far? I ve cleaned the MAF sensor. Checked for links in the intake. when I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant roughly 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I tolerate the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know past I link up you? No, I guess that is it.

I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. taking into account I unplug it and control the motor, the car runs gruff and at 850ish. I can lonely guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much control in the oscillate of rpm though? I think it only adjusts it just about 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you taking place 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 stirring and is warmed up? oftentimes in engine sham many factors may cause the similar symptom(s)
