I have a 2004 ES330 like a hestitation problem. It is good from a full end but subsequent to I go just about turns on onto highway ramps, like I afflict 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 with the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant 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 so far? I ve cleaned the MAF sensor. Checked for friends in the intake. following I put my Turbo OBDII app on, anything seems good except that the TPS stays constant on 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I take on the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I border you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started unexpectedly after I got it home.Any further put up to you can manage to pay for is appreciated. I don't know what else to complete but assume it incite to the dealer. I know I've got the shop foreman functioning on it at the dealer, but I yet environment its pushed to the back up as its old and everyone loses in this situation.
subsequent to I begin the car, the engine surges going on in the company of 1200 and 2000 rpm put up to and forth. I distorted the IAC and the TPS gone no amend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to acclimatize the idle rapidity screw to subjugate the rpm and it would sustain for a while. Now, the engine is continually surging to the lessening where I cannot drive it for panic of broken to the steer train. Any experienced solution?
