I have a 2004 ES330 like a hestitation problem. It is good from a full end but in the manner of I go something like turns upon onto highway ramps, later than I hurt 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 when the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery abundantly charged? With or without headlights on. Relatively extra 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 as a result far? I ve cleaned the MAF sensor. Checked for links in the intake. taking into consideration I put my Turbo OBDII app on, all seems fine except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I acknowledge the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know back I be close to you? No, I guess that is it.
I bought it in July, drove it home from LA (to Utah), and the problems started rapidly after I got it home.Any supplementary encourage you can offer is appreciated. I don't know what else to attain but acknowledge it encourage to the dealer. I know I've got the shop foreman on the go upon it at the dealer, but I still vibes its pushed to the back up as its dated and everyone loses in this situation.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you in the works 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 act out many factors may cause the same symptom(s)
