I have a 2004 ES330 like a hestitation problem. It is fine from a full end but following I go more or less turns upon onto highway ramps, afterward I sadden the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon past the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery fully charged? With or without headlights on. Relatively supplementary 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 suitably far? I ve cleaned the MAF sensor. Checked for links in the intake. with I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant almost 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I take the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I be close to you? No, I guess that is it.
Might next be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can accomplish a quick malfunction find if you unplug the meter and direct the engine without it. if the engine condition is the similar after that chances are the meter or the association to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can acquire coated once dirt exceeding period which later offsets the reading. Use some right of entry cleaner or brake cleaner to spray can onto the wires to sever the dirt upon no account be next to the wires in the same way as all as they are extremely fragile
Hello the TPS does have an effect upon switching the car into idle mode thus I'd recommend to create distinct the throttle dish is 100% closed and not slightly stuck gone carbon. and later get used to the TPS fittingly that the IDL stick is continuous to the E2 pin past the throttle is closed, and right to use circuit with the throttle is just cracked. Don't cause problems more or less any voltages, the IDL log on is the truly important one.
