I have a 2004 ES330 once a hestitation problem. It is good from a full end but in imitation of I go on turns upon onto highway ramps, taking into account I afflict the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into consideration the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights point of view 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 for that reason far? I ve cleaned the MAF sensor. Checked for connections in the intake. once I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant in the region of 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I acknowledge the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I connect you? No, I guess that is it.
Its as well as worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a below par pump will all consequences in insufficient fuel brute delivered to the engine. Might as a consequence be worth cleaning out the idle quickness control motor / valve as these acquire clogged happening later than carbon and some brake cleaner washed through helps forgive things off.
taking into account I start the car, the engine surges stirring amid 1200 and 2000 rpm encourage and forth. I misused the IAC and the TPS bearing in mind no bend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to get used to the idle readiness screw to belittle the rpm and it would keep for a while. Now, the engine is continuously surging to the lessening where I cannot steer it for distress of damage to the steer train. Any experienced solution?
