I have a 2004 ES330 when a hestitation problem. It is good from a full stop but behind I go as regards turns on onto highway ramps, in the manner of I pain 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 as soon as the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery thoroughly charged? With or without headlights on. Relatively other 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 associates in the intake. taking into consideration I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant as regards 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I undertake the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know past I border you? No, I guess that is it.
Its next 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 all upshot in insufficient fuel living thing delivered to the engine. Might next be worth cleaning out the idle rapidity manage motor / valve as these get clogged stirring in imitation of carbon and some brake cleaner washed through helps clear things off.
Hello the TPS does have an effect upon switching the car into idle mode as a result I'd recommend to make determined the throttle plate is 100% closed and not slightly ashore next carbon. and subsequently adapt the TPS correspondingly that the IDL fix is continuous to the E2 stick following the throttle is closed, and log on circuit later the throttle is just cracked. Don't cause problems roughly any voltages, the IDL way in is the in reality important one.
