I have a 2004 ES330 like a hestitation problem. It is fine from a full stop but once I go nearly turns on onto highway ramps, later than I depress 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 taking into consideration the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery thoroughly 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 appropriately far? I ve cleaned the MAF sensor. Checked for connections in the intake. taking into consideration I put my Turbo OBDII app on, anything seems good except that the TPS stays constant approximately 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I take on the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know previously I affix you? No, I guess that is it.
Might afterward be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can do a fast anomaly 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 link to it is faulty. Its along with worth cleaning the MAF sensor wires, as they can acquire coated later than dirt beyond era which then offsets the reading. Use some retrieve cleaner or brake cleaner to vaporizer onto the wires to cut off the dirt upon no account adjoin the wires bearing in mind whatever as they are certainly fragile
I don't have any check engine lights unless I unplug the MAF sensor. next the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is moreover an intermittent popping unquestionable coming at idle.
