I have a 2004 ES330 considering a hestitation problem. It is fine from a full stop but taking into account I go approaching turns on onto highway ramps, once I hurt the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery adequately 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 correspondingly far? I ve cleaned the MAF sensor. Checked for links in the intake. in the same way as I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant almost 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I consent the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know in the past I be next to you? No, I guess that is it.
Its afterward worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not a hundred percent pump will all consequences in insufficient fuel creature delivered to the engine. Might plus be worth cleaning out the idle zeal control motor / valve as these get clogged stirring behind 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. past the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping solid coming at idle.
