I have a 2004 ES330 like a hestitation problem. It is fine from a full stop but following I go in relation to turns upon onto highway ramps, when I distress 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 like the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery thoroughly charged? With or without headlights on. Relatively other 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 connections in the intake. gone I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant more or less 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I take the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know back I be next to you? No, I guess that is it.
Might then be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can get a quick anomaly find if you unplug the meter and direct the engine without it. if the engine condition is the thesame subsequently chances are the meter or the link to it is faulty. Its after that worth cleaning the MAF sensor wires, as they can get coated in the same way as dirt on top of grow old which then offsets the reading. Use some retrieve cleaner or brake cleaner to spray can onto the wires to sever the dirt upon no account be next to the wires considering whatever as they are utterly fragile
Hello the TPS does have an effect on switching the car into idle mode as a result I'd suggest to make clear the throttle dish is 100% closed and not slightly grounded gone carbon. and subsequently acclimatize the TPS consequently that the IDL fasten is continuous to the E2 stick afterward the throttle is closed, and way in circuit in the same way as the throttle is just cracked. Don't badly affect more or less any voltages, the IDL right to use is the essentially important one.
