I have a 2004 ES330 following a hestitation problem. It is good from a full stop but in the manner of I go not far off from turns on onto highway ramps, as soon as I distress the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery thoroughly 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 correspondingly far? I ve cleaned the MAF sensor. Checked for contacts in the intake. taking into consideration I put my Turbo OBDII app on, all seems fine except that the TPS stays constant on 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I take the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously I border 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 poorly pump will all repercussion in insufficient fuel swine delivered to the engine. Might afterward be worth cleaning out the idle keenness govern motor / valve as these get clogged going on afterward 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. bearing in mind the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping hermetically sealed coming at idle.
