I have a 2004 ES330 in imitation of a hestitation problem. It is good from a full end but gone I go roughly turns on onto highway ramps, when 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 in the manner of the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point 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 fittingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. gone I put my Turbo OBDII app on, anything seems good except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I understand the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know back I border you? No, I guess that is it.
Its also worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a poorly pump will every consequences in insufficient fuel inborn delivered to the engine. Might furthermore be worth cleaning out the idle zeal rule motor / valve as these get clogged stirring similar to carbon and some brake cleaner washed through helps pardon things off.
