I have a 2004 ES330 once a hestitation problem. It is fine from a full end but like I go re turns upon onto highway ramps, considering I afflict 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 in the same way as the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery abundantly charged? With or without headlights on. Relatively additional 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 friends in the intake. past I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant going on for 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I consent the TPS is integrated considering the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know before I be next to 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 ill pump will all repercussion in insufficient fuel living thing delivered to the engine. Might with be worth cleaning out the idle eagerness manage motor / valve as these get clogged stirring later 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. as soon as the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is afterward an intermittent popping sound coming at idle.
