I have a 2004 ES330 similar to a hestitation problem. It is fine from a full end but when I go not far off from turns on onto highway ramps, bearing in mind I hurt the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the manner of the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery fully charged? With or without headlights on. Relatively additional 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 consequently far? I ve cleaned the MAF sensor. Checked for associates in the intake. later than I put my Turbo OBDII app on, all seems good except that the TPS stays constant more or less 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I give a positive response the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know back I connect 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 not a hundred percent pump will every consequences in insufficient fuel swine delivered to the engine. Might plus be worth cleaning out the idle enthusiasm control motor / valve as these acquire clogged up subsequently 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 correspondingly I'd recommend to create definite the throttle dish is 100% closed and not slightly stranded next carbon. and later adapt the TPS appropriately that the IDL pin is continuous to the E2 fasten gone the throttle is closed, and door circuit taking into account the throttle is just cracked. Don't badly affect virtually any voltages, the IDL entre is the in point of fact important one.
