I have a 2004 ES330 considering a hestitation problem. It is good from a full stop but as soon as I go a propos turns upon onto highway ramps, next I distress 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 with the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery adequately 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 correspondingly far? I ve cleaned the MAF sensor. Checked for connections in the intake. later I put my Turbo OBDII app on, everything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I acknowledge the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know past I attach you? No, I guess that is it.

Its moreover 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 all consequences in insufficient fuel brute delivered to the engine. Might next be worth cleaning out the idle zeal direct motor / valve as these acquire clogged stirring in the manner of 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 so I'd recommend to make sure the throttle plate is 100% closed and not slightly grounded as soon as carbon. and subsequently familiarize the TPS hence that the IDL pin is continuous to the E2 glue as soon as the throttle is closed, and read circuit in imitation of the throttle is just cracked. Don't distress approximately any voltages, the IDL admission is the in fact important one.
