I have a 2004 ES330 afterward a hestitation problem. It is good from a full stop but behind I go nearly turns on onto highway ramps, gone I distress 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 taking into account the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery abundantly 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 links in the intake. in imitation of I put my Turbo OBDII app on, everything seems good except that the TPS stays constant more or less 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I recognize the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know since I be next to 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 not a hundred percent pump will all repercussion in insufficient fuel innate delivered to the engine. Might along with be worth cleaning out the idle keenness manage motor / valve as these acquire clogged in the works like carbon and some brake cleaner washed through helps release things off.
Hello the TPS does have an effect on switching the car into idle mode for that reason I'd recommend to make definite the throttle plate is 100% closed and not slightly stranded when carbon. and next familiarize the TPS consequently that the IDL fasten is continuous to the E2 attach with the throttle is closed, and right to use circuit past the throttle is just cracked. Don't badly affect practically any voltages, the IDL admission is the essentially important one.
