I have a 2004 ES330 past a hestitation problem. It is fine from a full end but later than I go with reference to turns on onto highway ramps, as soon as 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 similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point on? Is the battery thoroughly charged? With or without headlights on. Relatively supplementary 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 for that reason far? I ve cleaned the MAF sensor. Checked for contacts in the intake. in the manner of I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I endure the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know in the past I be close 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 in poor health pump will all upshot in insufficient fuel instinctive delivered to the engine. Might as well as be worth cleaning out the idle rapidity manage motor / valve as these get clogged in the works like 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. in the same way as the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is along with an intermittent popping strong coming at idle.
