I have a 2004 ES330 as soon as a hestitation problem. It is good from a full stop but considering I go something like turns on onto highway ramps, with I distress 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 in the manner of the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery thoroughly charged? With or without headlights on. Relatively new 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 connections in the intake. bearing in mind I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant as regards 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I say yes the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know past I attach you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started hastily after I got it home.Any further encourage you can pay for is appreciated. I don't know what else to reach but say you will it support to the dealer. I know I've got the shop foreman in force upon it at the dealer, but I nevertheless setting its pushed to the incite as its obsolescent and everyone loses in this situation.
later I start the car, the engine surges occurring amid 1200 and 2000 rpm encourage and forth. I misrepresented the IAC and the TPS past no fine-tune in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adjust the idle rapidity screw to degrade the rpm and it would withhold for a while. Now, the engine is at all times surging to the tapering off where I cannot drive it for panic of damage to the steer train. Any experienced solution?
