I have a 2004 ES330 considering a hestitation problem. It is fine from a full end but bearing in mind I go almost turns on onto highway ramps, taking into consideration I afflict the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon when the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery thoroughly charged? With or without headlights on. Relatively additional 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 links in the intake. in imitation of I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant on the order of 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I receive the TPS is integrated as soon as the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know back I attach 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 ill pump will all result in insufficient fuel visceral delivered to the engine. Might along with be worth cleaning out the idle keenness run motor / valve as these get clogged up considering carbon and some brake cleaner washed through helps forgive things off.
in the same way as I start the car, the engine surges taking place between 1200 and 2000 rpm back up and forth. I misused the IAC and the TPS in the manner of no bend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adjust the idle keenness screw to demean the rpm and it would withhold for a while. Now, the engine is continually surging to the narrowing where I cannot drive it for warning of damage to the drive train. Any experienced solution?
