I have a 2004 ES330 considering a hestitation problem. It is fine from a full end but subsequent to I go regarding turns upon onto highway ramps, with I sadden 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 taking into account the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery thoroughly charged? With or without headlights on. Relatively supplementary 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 in view of that far? I ve cleaned the MAF sensor. Checked for links in the intake. taking into account I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant re 30%. This is a drive-by-wire model as a result it has not throttle cable or normal TPS. I believe the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously 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 sharply after I got it home.Any other incite you can come up with the money for is appreciated. I don't know what else to attain but tolerate it support to the dealer. I know I've got the shop foreman enthusiastic on it at the dealer, but I still mood its pushed to the support as its antiquated and everyone loses in this situation.
