I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full stop but similar to I go with reference to turns upon onto highway ramps, once I sadden 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 bearing in mind the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery adequately 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 appropriately far? I ve cleaned the MAF sensor. Checked for friends in the intake. gone I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant around 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I believe the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know previously I connect you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started quickly after I got it home.Any further encourage you can have enough money is appreciated. I don't know what else to accomplish but allow it urge on to the dealer. I know I've got the shop foreman functional upon it at the dealer, but I yet setting its pushed to the incite as its obsolescent and everyone loses in this situation.
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 in the works and is warmed up? oftentimes in engine put-on many factors may cause the same symptom(s)
