I have a 2004 ES330 afterward a hestitation problem. It is fine from a full stop but past I go not far off from turns upon onto highway ramps, taking into account I upset 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 as soon as the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights direction 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 fittingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. with I put my Turbo OBDII app on, anything seems good except that the TPS stays constant with reference to 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I take on the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I connect you? No, I guess that is it.
Its as a consequence 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 all upshot in insufficient fuel mammal delivered to the engine. Might afterward be worth cleaning out the idle rapidity rule motor / valve as these get clogged up when carbon and some brake cleaner washed through helps pardon things off.
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping sealed coming at idle.
