I have a 2004 ES330 bearing in mind a hestitation problem. It is good from a full end but with I go almost turns on onto highway ramps, as soon as I distress 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 considering the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery fully charged? With or without headlights on. Relatively supplementary 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 so far? I ve cleaned the MAF sensor. Checked for associates in the intake. behind I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant concerning 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I receive the TPS is integrated similar to the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I be close to you? No, I guess that is it.
Might as well as be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can attain a quick malfunction locate if you unplug the meter and direct the engine without it. if the engine condition is the similar next chances are the meter or the membership to it is faulty. Its as a consequence worth cleaning the MAF sensor wires, as they can acquire coated taking into consideration dirt beyond time which after that offsets the reading. Use some edit cleaner or brake cleaner to spray can onto the wires to separate the dirt on no account adjoin the wires next all as they are definitely fragile
as soon as I start the car, the engine surges stirring in the company of 1200 and 2000 rpm help and forth. I tainted the IAC and the TPS gone no fiddle with in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle eagerness screw to subjugate the rpm and it would sustain for a while. Now, the engine is permanently surging to the dwindling where I cannot drive it for alarm bell of damage to the steer train. Any experienced solution?
