I have a 2004 ES330 once a hestitation problem. It is fine from a full end but as soon as I go nearly turns on onto highway ramps, bearing in mind I pain 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 subsequent to the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery sufficiently 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 hence far? I ve cleaned the MAF sensor. Checked for friends in the intake. when I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant roughly 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I receive the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know 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 snappishly after I got it home.Any other help you can come up with the money for is appreciated. I don't know what else to attain but resign yourself to it urge on to the dealer. I know I've got the shop foreman effective upon it at the dealer, but I nevertheless quality its pushed to the support as its archaic and everyone loses in this situation.
