I have a 2004 ES330 next a hestitation problem. It is good from a full end but in the manner of I go vis--vis turns upon onto highway ramps, like I afflict 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 behind the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery sufficiently charged? With or without headlights on. Relatively extra 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 appropriately far? I ve cleaned the MAF sensor. Checked for associates in the intake. subsequent to I put my Turbo OBDII app on, everything seems good except that the TPS stays constant almost 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I believe the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know back I be close to you? No, I guess that is it.
Its plus 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 outcome in insufficient fuel brute delivered to the engine. Might after that be worth cleaning out the idle speed manage motor / valve as these acquire clogged in the works like carbon and some brake cleaner washed through helps free things off.
