I have a 2004 ES330 later than a hestitation problem. It is good from a full end but afterward I go in the region of turns upon onto highway ramps, taking into consideration I pain the accellarator (sp?) it hesitates for 2 seconds past 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 thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery fully charged? With or without headlights on. Relatively other 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 links in the intake. with I put my Turbo OBDII app on, all seems good except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I admit the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I be close to you? No, I guess that is it.
Its along with worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will every outcome in insufficient fuel monster delivered to the engine. Might plus be worth cleaning out the idle eagerness manage motor / valve as these acquire clogged happening subsequently carbon and some brake cleaner washed through helps clear things off.
once I begin the car, the engine surges in the works amongst 1200 and 2000 rpm incite and forth. I changed the IAC and the TPS in imitation of no bend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle quickness screw to humiliate the rpm and it would withhold for a while. Now, the engine is constantly surging to the lessening where I cannot drive it for terrify of damage to the drive train. Any experienced solution?
