I have a 2004 ES330 similar to a hestitation problem. It is good from a full stop but taking into account I go roughly turns upon onto highway ramps, taking into account I distress the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon with the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery fully 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 fittingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. past I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant with reference to 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I understand the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know in the past I border you? No, I guess that is it.
I bought it in July, drove it home from LA (to Utah), and the problems started hastily after I got it home.Any other incite you can offer is appreciated. I don't know what else to do but take it assist to the dealer. I know I've got the shop foreman functional on it at the dealer, but I nevertheless vibes its pushed to the help as its old and everyone loses in this situation.
