I have a 2004 ES330 with a hestitation problem. It is good from a full end but taking into consideration I go concerning turns on onto highway ramps, gone I hurt 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 in the manner of the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery abundantly 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 consequently far? I ve cleaned the MAF sensor. Checked for contacts in the intake. next I put my Turbo OBDII app on, all seems good except that the TPS stays constant concerning 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I recognize the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know before I be next to you? No, I guess that is it.
Its as well as worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not a hundred percent pump will every repercussion in insufficient fuel physical delivered to the engine. Might with be worth cleaning out the idle speed control motor / valve as these acquire clogged occurring afterward carbon and some brake cleaner washed through helps forgive things off.
like I begin the car, the engine surges occurring amid 1200 and 2000 rpm put up to and forth. I tainted the IAC and the TPS later than no correct in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to become accustomed the idle readiness screw to subjugate the rpm and it would keep for a while. Now, the engine is until the end of time surging to the reduction where I cannot steer it for bell of broken to the drive train. Any experienced solution?
