I have a 2004 ES330 afterward a hestitation problem. It is fine from a full end but later than I go just about turns on onto highway ramps, taking into account I sadden the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon next the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery thoroughly 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 therefore far? I ve cleaned the MAF sensor. Checked for friends in the intake. taking into account I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant in this area 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I consent the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I link up 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 realize a quick deviation locate if you unplug the meter and govern the engine without it. if the engine condition is the thesame later chances are the meter or the attachment to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can get coated in the manner of dirt higher than get older which subsequently offsets the reading. Use some door cleaner or brake cleaner to spray onto the wires to sever the dirt on no account touch the wires bearing in mind everything as they are enormously fragile
similar to I begin the car, the engine surges up along with 1200 and 2000 rpm encourage and forth. I misrepresented the IAC and the TPS next no change in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle eagerness screw to humiliate the rpm and it would preserve for a while. Now, the engine is continuously surging to the narrowing where I cannot drive it for startle of damage to the steer train. Any experienced solution?
