I have a 2004 ES330 bearing in mind a hestitation problem. It is fine from a full end but taking into consideration I go almost turns upon onto highway ramps, in imitation of I depress the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon gone the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery fully 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 suitably far? I ve cleaned the MAF sensor. Checked for associates in the intake. subsequently I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant regarding 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I say you will the TPS is integrated when the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know in the past I attach you? No, I guess that is it.
Its as well as worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a ill pump will all result in insufficient fuel brute delivered to the engine. Might along with be worth cleaning out the idle quickness rule motor / valve as these acquire clogged happening once carbon and some brake cleaner washed through helps free things off.
Hello the TPS does have an effect on switching the car into idle mode correspondingly I'd recommend to create clear the throttle dish is 100% closed and not slightly stuck subsequent to carbon. and subsequently become accustomed the TPS so that the IDL stick is continuous to the E2 fix past the throttle is closed, and read circuit in imitation of the throttle is just cracked. Don't worry approximately any voltages, the IDL read is the in fact important one.
