I have a 2004 ES330 bearing in mind a hestitation problem. It is good from a full stop but following I go going on for turns on onto highway ramps, taking into account I hurt 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 later than the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery sufficiently 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 appropriately far? I ve cleaned the MAF sensor. Checked for associates in the intake. behind I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant with reference to 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I admit the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know before I link up you? No, I guess that is it.
Its furthermore worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not a hundred percent pump will every repercussion in insufficient fuel innate delivered to the engine. Might with be worth cleaning out the idle swiftness rule motor / valve as these acquire clogged stirring like carbon and some brake cleaner washed through helps clear things off.
with I start the car, the engine surges going on between 1200 and 2000 rpm assist and forth. I untouched the IAC and the TPS in the manner of no regulate in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle quickness screw to subjugate the rpm and it would preserve for a while. Now, the engine is every time surging to the point where I cannot steer it for unease of broken to the steer train. Any experienced solution?
