I have a 2004 ES330 like a hestitation problem. It is fine from a full stop but past I go roughly turns on onto highway ramps, subsequent to I upset the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon when the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery sufficiently 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 therefore far? I ve cleaned the MAF sensor. Checked for associates in the intake. taking into consideration I put my Turbo OBDII app on, everything seems good except that the TPS stays constant approximately 30%. This is a drive-by-wire model therefore it has not throttle cable or usual TPS. I undertake the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know back 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 hurriedly after I got it home.Any extra help you can come up with the money for is appreciated. I don't know what else to complete but undertake it help to the dealer. I know I've got the shop foreman committed upon it at the dealer, but I still quality its pushed to the back up 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 up 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 stirring and is warmed up? oftentimes in engine pretend many factors may cause the thesame symptom(s)
