I have a 2004 ES330 afterward a hestitation problem. It is fine from a full end but past I go not far off from turns upon onto highway ramps, past I afflict 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 taking into account the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery abundantly charged? With or without headlights on. Relatively other 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 associates in the intake. like I put my Turbo OBDII app on, anything seems good except that the TPS stays constant around 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I endure the TPS is integrated gone the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know past I be close to you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started immediately after I got it home.Any supplementary urge on you can give is appreciated. I don't know what else to reach but allow it urge on to the dealer. I know I've got the shop foreman committed on it at the dealer, but I still vibes its pushed to the assist as its old-fashioned and everyone loses in this situation.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you happening to date on all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms going on and is warmed up? oftentimes in engine performance many factors may cause the same symptom(s)
