I have a 2004 ES330 as soon as a hestitation problem. It is fine from a full end but later I go in this area turns on onto highway ramps, next I upset 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 once the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery sufficiently 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 correspondingly far? I ve cleaned the MAF sensor. Checked for links in the intake. taking into consideration 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 correspondingly it has not throttle cable or normal TPS. I take on the TPS is integrated in the manner of the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I connect you? No, I guess that is it.
Its in addition to worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a sick pump will every result in insufficient fuel beast delivered to the engine. Might plus be worth cleaning out the idle zeal rule motor / valve as these get clogged taking place like 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. in imitation of the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping solid coming at idle.
