I have a 2004 ES330 past a hestitation problem. It is good from a full end but following I go more or less turns on onto highway ramps, in the same way as I distress 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 thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery sufficiently charged? With or without headlights on. Relatively new 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 thus far? I ve cleaned the MAF sensor. Checked for friends in the intake. when I put my Turbo OBDII app on, everything seems good except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I give a positive response the TPS is integrated as soon as the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know previously I connect you? No, I guess that is it.
Its after that 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 every outcome in insufficient fuel brute delivered to the engine. Might afterward be worth cleaning out the idle keenness control motor / valve as these get clogged going on gone 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 make clear the throttle plate is 100% closed and not slightly beached taking into account carbon. and subsequently familiarize the TPS correspondingly that the IDL fix is continuous to the E2 stick bearing in mind the throttle is closed, and gate circuit once the throttle is just cracked. Don't upset nearly any voltages, the IDL edit is the truly important one.
