I have a 2004 ES330 taking into account a hestitation problem. It is good from a full stop but taking into consideration I go in the region of turns on onto highway ramps, once I hurt 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 similar to the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery sufficiently 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 consequently far? I ve cleaned the MAF sensor. Checked for connections in the intake. later than I put my Turbo OBDII app on, anything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I resign yourself to the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know before I border you? No, I guess that is it.
Its after that worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will every outcome in insufficient fuel being delivered to the engine. Might furthermore be worth cleaning out the idle promptness run motor / valve as these acquire clogged happening in imitation of carbon and some brake cleaner washed through helps clear things off.
I don't have any check engine lights unless I unplug the MAF sensor. similar to the MAF is plugged in subsequently the car will stall unless I put my foot on the accelerator. There is as a consequence an intermittent popping hermetic coming at idle.
