I have a 2004 ES330 past a hestitation problem. It is fine from a full end but once I go with reference to turns on onto highway ramps, later I depress 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 later than the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery sufficiently 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 as a result far? I ve cleaned the MAF sensor. Checked for contacts in the intake. once I put my Turbo OBDII app on, all seems fine except that the TPS stays constant in the region of 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I undertake the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know before I affix 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 poorly pump will all consequences in insufficient fuel swine delivered to the engine. Might furthermore be worth cleaning out the idle enthusiasm rule motor / valve as these get clogged in the works similar to carbon and some brake cleaner washed through helps free things off.
