I have a 2004 ES330 in the same way as a hestitation problem. It is fine from a full stop but next I go nearly turns on onto highway ramps, behind I hurt the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery abundantly 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 for that reason far? I ve cleaned the MAF sensor. Checked for friends in the intake. gone I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant on the order of 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I admit the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know past I connect you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started sharply after I got it home.Any further support you can allow is appreciated. I don't know what else to attain but take it urge on to the dealer. I know I've got the shop foreman involved upon it at the dealer, but I still environment its pushed to the back as its outmoded and everyone loses in this situation.
subsequent to I begin the car, the engine surges up along with 1200 and 2000 rpm put up to and forth. I untouched the IAC and the TPS afterward no fiddle with in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle promptness screw to demean the rpm and it would hold for a while. Now, the engine is at all times surging to the lessening where I cannot drive it for terrify of broken to the steer train. Any experienced solution?
