I have a 2004 ES330 next a hestitation problem. It is fine from a full stop but with I go a propos turns upon onto highway ramps, behind I upset the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon once the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery adequately charged? With or without headlights on. Relatively other 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 links in the intake. bearing in mind I put my Turbo OBDII app on, anything seems good except that the TPS stays constant around 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I put up with the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know since I be next to you? No, I guess that is it.
Its after that 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 outcome in insufficient fuel innate delivered to the engine. Might plus be worth cleaning out the idle quickness manage motor / valve as these get clogged stirring subsequent to carbon and some brake cleaner washed through helps free things off.
I don't have any check engine lights unless I unplug the MAF sensor. in imitation of the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is after that an intermittent popping sound coming at idle.
