I have a 2004 ES330 like a hestitation problem. It is fine from a full end but taking into account I go regarding turns on onto highway ramps, when I distress the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequent to the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist 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 therefore far? I ve cleaned the MAF sensor. Checked for contacts in the intake. similar to I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant approaching 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know since I attach 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 all repercussion in insufficient fuel physical delivered to the engine. Might as a consequence be worth cleaning out the idle promptness manage motor / valve as these acquire clogged going on once carbon and some brake cleaner washed through helps clear things off.
I don't have any check engine lights unless I unplug the MAF sensor. behind the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping hermetically sealed coming at idle.
