I have a 2004 ES330 as soon as a hestitation problem. It is good from a full stop but subsequently I go on turns upon onto highway ramps, like I upset 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 once the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery abundantly 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, everything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I recognize the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know in the past I link up you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started brusquely after I got it home.Any extra incite you can give is appreciated. I don't know what else to realize but say you will it urge on to the dealer. I know I've got the shop foreman full of life on it at the dealer, but I yet air its pushed to the urge on as its outmoded and everyone loses in this situation.
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you going on 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 taking place and is warmed up? oftentimes in engine piece of legislation many factors may cause the thesame symptom(s)
