I have a 2004 ES330 taking into consideration a hestitation problem. It is good from a full end but gone I go all but turns upon onto highway ramps, taking into consideration I distress 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 in the manner of the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery thoroughly 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 suitably far? I ve cleaned the MAF sensor. Checked for links in the intake. with I put my Turbo OBDII app on, all seems fine except that the TPS stays constant roughly 30%. This is a drive-by-wire model as a result it has not throttle cable or normal TPS. I bow to the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know back I connect you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. with I unplug it and govern the motor, the car runs brusque and at 850ish. I can unaccompanied guess that my additional 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 govern in the exchange of rpm though? I think it single-handedly adjusts it a propos 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you stirring to date on every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms up and is warmed up? oftentimes in engine play many factors may cause the similar symptom(s)
