I have a 2004 ES330 taking into consideration a hestitation problem. It is fine from a full end but once I go approximately turns upon onto highway ramps, taking into consideration I pain 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 as soon as the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point on? Is the battery sufficiently 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 thus far? I ve cleaned the MAF sensor. Checked for associates in the intake. in imitation of I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in this area 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I put up with the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know past I attach 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 realize a fast anomaly locate if you unplug the meter and run the engine without it. if the engine condition is the similar later chances are the meter or the link to it is faulty. Its furthermore worth cleaning the MAF sensor wires, as they can acquire coated following dirt beyond mature which next offsets the reading. Use some way in cleaner or brake cleaner to spray onto the wires to surgically remove the dirt on no account be adjacent to the wires like whatever as they are enormously fragile
taking into account I start the car, the engine surges stirring along with 1200 and 2000 rpm assist and forth. I misrepresented the IAC and the TPS in imitation of no modify in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle speed screw to subjugate the rpm and it would hold for a while. Now, the engine is continuously surging to the reduction where I cannot steer it for unease of broken to the drive train. Any experienced solution?
