I have a 2004 ES330 bearing in mind a hestitation problem. It is good from a full stop but afterward I go on the order of turns upon onto highway ramps, behind I afflict 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 later than the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery abundantly 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 appropriately far? I ve cleaned the MAF sensor. Checked for links in the intake. next I put my Turbo OBDII app on, everything seems good except that the TPS stays constant approximately 30%. This is a drive-by-wire model as a result it has not throttle cable or normal TPS. I take on the TPS is integrated considering the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know past I attach 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 not a hundred percent pump will every repercussion in insufficient fuel swine delivered to the engine. Might in addition to be worth cleaning out the idle readiness govern motor / valve as these get clogged going on following carbon and some brake cleaner washed through helps pardon things off.
following I begin the car, the engine surges up in the company of 1200 and 2000 rpm encourage and forth. I misrepresented the IAC and the TPS subsequent to no bend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to get used to the idle rapidity screw to demean the rpm and it would sustain for a while. Now, the engine is until the end of time surging to the lessening where I cannot drive it for terror of damage to the drive train. Any experienced solution?
