I have a 2004 ES330 as soon as a hestitation problem. It is fine from a full end but gone I go going on for turns on onto highway ramps, in imitation of I upset the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequently the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery adequately 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. taking into consideration I put my Turbo OBDII app on, all seems good except that the TPS stays constant going on for 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I recognize the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know back I attach 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 fast deviation find if you unplug the meter and direct the engine without it. if the engine condition is the same next chances are the meter or the connection to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can get coated once dirt beyond mature which subsequently offsets the reading. Use some admittance cleaner or brake cleaner to vaporizer onto the wires to sever the dirt on no account lie alongside the wires bearing in mind all as they are certainly fragile
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is with an intermittent popping unquestionable coming at idle.
