I have a 2004 ES330 subsequently a hestitation problem. It is fine from a full end but when I go with reference to turns on onto highway ramps, afterward I distress the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the same way as the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery adequately 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 in view of that far? I ve cleaned the MAF sensor. Checked for associates in the intake. behind I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant approximately 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I assume the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know back I be close to you? No, I guess that is it.
Its furthermore worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a in poor health pump will every result in insufficient fuel bodily delivered to the engine. Might afterward be worth cleaning out the idle rapidity rule motor / valve as these acquire clogged in the works later than carbon and some brake cleaner washed through helps release things off.
Hello the TPS does have an effect upon switching the car into idle mode therefore I'd recommend to make definite the throttle plate is 100% closed and not slightly stranded behind carbon. and subsequently adapt the TPS fittingly that the IDL pin is continuous to the E2 attach taking into consideration the throttle is closed, and read circuit in the same way as the throttle is just cracked. Don't bother very nearly any voltages, the IDL get into is the essentially important one.
