I have a 2004 ES330 later than a hestitation problem. It is good from a full stop but afterward I go something like turns on onto highway ramps, afterward I afflict 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 subsequently the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery fully 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 for that reason far? I ve cleaned the MAF sensor. Checked for connections in the intake. when I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant going on for 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I consent the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know since I link up 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 sick pump will all result in insufficient fuel subconscious delivered to the engine. Might also be worth cleaning out the idle eagerness govern motor / valve as these get clogged going on bearing in mind 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 in view of that I'd recommend to make clear the throttle dish is 100% closed and not slightly ashore in the same way as carbon. and then become accustomed the TPS in view of that that the IDL fasten is continuous to the E2 stick similar to the throttle is closed, and entre circuit subsequently the throttle is just cracked. Don't upset nearly any voltages, the IDL right to use is the essentially important one.
