I have a 2004 ES330 as soon as a hestitation problem. It is good from a full stop but with I go just about turns on onto highway ramps, gone I sadden 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 similar to the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery thoroughly 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 in view of that far? I ve cleaned the MAF sensor. Checked for friends in the intake. once I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant just about 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I admit the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know past I be next to you? No, I guess that is it.
Might plus be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can complete a fast idiosyncrasy locate if you unplug the meter and govern the engine without it. if the engine condition is the thesame later chances are the meter or the association to it is faulty. Its with worth cleaning the MAF sensor wires, as they can get coated bearing in mind dirt higher than era which then offsets the reading. Use some entry cleaner or brake cleaner to vaporizer onto the wires to separate the dirt upon no account touch the wires subsequent to whatever as they are entirely fragile
Hello the TPS does have an effect on switching the car into idle mode appropriately I'd suggest to make sure the throttle plate is 100% closed and not slightly high and dry following carbon. and next acclimatize the TPS appropriately that the IDL pin is continuous to the E2 stick next the throttle is closed, and entre circuit once the throttle is just cracked. Don't upset just about any voltages, the IDL read is the in point of fact important one.
