I have a 2004 ES330 subsequent to a hestitation problem. It is fine from a full end but gone I go just about turns on onto highway ramps, in imitation of I hurt the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery fully 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 correspondingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. behind I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in relation to 30%. This is a drive-by-wire model for that reason it has not throttle cable or usual TPS. I take on the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know in the past I affix you? No, I guess that is it.
Its then 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 mammal delivered to the engine. Might in addition to be worth cleaning out the idle readiness control motor / valve as these get clogged happening subsequent to carbon and some brake cleaner washed through helps forgive things off.
Hello the TPS does have an effect upon switching the car into idle mode therefore I'd recommend to create definite the throttle plate is 100% closed and not slightly stranded later carbon. and next become accustomed the TPS appropriately that the IDL pin is continuous to the E2 glue next the throttle is closed, and approach circuit later the throttle is just cracked. Don't trouble virtually any voltages, the IDL approach is the essentially important one.
