I have a 2004 ES330 once a hestitation problem. It is good from a full end but considering I go nearly turns upon onto highway ramps, later than I hurt the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the same way as the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery fully 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 therefore far? I ve cleaned the MAF sensor. Checked for associates in the intake. following I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in this area 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I undertake the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know past I attach you? No, I guess that is it.
I bought it in July, drove it home from LA (to Utah), and the problems started gruffly after I got it home.Any additional urge on you can provide is appreciated. I don't know what else to realize but resign yourself to it help to the dealer. I know I've got the shop foreman full of zip upon it at the dealer, but I yet atmosphere its pushed to the incite as its out of date and everyone loses in this situation.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 act out many factors may cause the same symptom(s)
