I have a 2004 ES330 later a hestitation problem. It is fine from a full stop but taking into consideration I go vis--vis turns upon onto highway ramps, as soon as I hurt the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery sufficiently charged? With or without headlights on. Relatively further 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 connections in the intake. next I put my Turbo OBDII app on, all seems fine except that the TPS stays constant roughly 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I acknowledge the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know previously I link up 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 in poor health pump will every upshot in insufficient fuel creature delivered to the engine. Might after that be worth cleaning out the idle quickness rule motor / valve as these acquire clogged going on taking into account carbon and some brake cleaner washed through helps free things off.
I don't have any check engine lights unless I unplug the MAF sensor. subsequent to the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping sealed coming at idle.
