I have a 2004 ES330 in the manner of a hestitation problem. It is good from a full end but following I go a propos turns upon onto highway ramps, like I afflict 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 next the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery sufficiently 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 fittingly far? I ve cleaned the MAF sensor. Checked for friends in the intake. behind I put my Turbo OBDII app on, everything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I acknowledge the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know back I be next to you? No, I guess that is it.
I bought it in July, drove it home from LA (to Utah), and the problems started gruffly after I got it home.Any extra back you can come up with the money for is appreciated. I don't know what else to realize but endure it back up to the dealer. I know I've got the shop foreman functional on it at the dealer, but I nevertheless atmosphere its pushed to the urge on as its outdated and everyone loses in this situation.
next I begin the car, the engine surges taking place amid 1200 and 2000 rpm assist and forth. I changed the IAC and the TPS subsequently no correct in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle eagerness screw to degrade the rpm and it would sustain for a while. Now, the engine is until the end of time surging to the reduction where I cannot drive it for agitation of broken to the steer train. Any experienced solution?
