I have a 2004 ES330 with a hestitation problem. It is fine from a full end but afterward I go concerning turns on onto highway ramps, in the manner of I hurt 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 like the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery abundantly charged? With or without headlights on. Relatively new 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 hence far? I ve cleaned the MAF sensor. Checked for friends in the intake. later than I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant on the order of 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I agree to the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know back I connect 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 complete a fast malformation find 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 association to it is faulty. Its then worth cleaning the MAF sensor wires, as they can acquire coated like dirt greater than time which subsequently offsets the reading. Use some entry cleaner or brake cleaner to spray onto the wires to surgically remove the dirt upon no account be adjacent to the wires next everything as they are totally fragile
I don't have any check engine lights unless I unplug the MAF sensor. gone the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is with an intermittent popping sound coming at idle.
