I have a 2004 ES330 afterward a hestitation problem. It is good from a full stop but taking into consideration I go regarding turns upon onto highway ramps, in the same way as I pain the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon with the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery adequately 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 in view of that far? I ve cleaned the MAF sensor. Checked for friends in the intake. like I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I believe the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously I connect you? No, I guess that is it.
Its with worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not at your best pump will all outcome in insufficient fuel brute delivered to the engine. Might as well as be worth cleaning out the idle promptness direct motor / valve as these acquire clogged stirring similar to carbon and some brake cleaner washed through helps forgive things off.
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is in addition to an intermittent popping hermetic coming at idle.
