I have a 2004 ES330 afterward a hestitation problem. It is good from a full end but next I go approaching turns on onto highway ramps, like I depress 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 afterward the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights direction on? Is the battery thoroughly charged? With or without headlights on. Relatively further 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 fittingly far? I ve cleaned the MAF sensor. Checked for friends in the intake. once I put my Turbo OBDII app on, all seems fine except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I tolerate the TPS is integrated when 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 with 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 upshot in insufficient fuel subconscious delivered to the engine. Might as a consequence be worth cleaning out the idle readiness govern motor / valve as these acquire clogged going on gone carbon and some brake cleaner washed through helps clear things off.
Hello the TPS does have an effect on switching the car into idle mode suitably I'd recommend to create certain the throttle plate is 100% closed and not slightly beached later than carbon. and next adapt the TPS in view of that that the IDL fasten is continuous to the E2 stick afterward the throttle is closed, and open circuit later than the throttle is just cracked. Don't upset practically any voltages, the IDL approach is the truly important one.
