I have a 2004 ES330 following a hestitation problem. It is good from a full stop but once I go approximately turns upon onto highway ramps, once I upset the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon following the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery fully 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 consequently far? I ve cleaned the MAF sensor. Checked for friends in the intake. in imitation of I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant not far off from 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I agree to the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I border 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 anomaly locate if you unplug the meter and rule the engine without it. if the engine condition is the same after that chances are the meter or the connection to it is faulty. Its moreover worth cleaning the MAF sensor wires, as they can get coated afterward dirt higher than become old which after that offsets the reading. Use some edit cleaner or brake cleaner to spray can onto the wires to cut off the dirt upon no account adjoin the wires gone everything as they are utterly fragile
I don't have any check engine lights unless I unplug the MAF sensor. in the manner of the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping unquestionable coming at idle.
