I have a 2004 ES330 considering a hestitation problem. It is fine from a full end but in the same way as I go vis–vis turns upon onto highway ramps, past I upset 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 similar to the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery thoroughly 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 thus far? I ve cleaned the MAF sensor. Checked for associates in the intake. behind I put my Turbo OBDII app on, all seems good except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I agree to the TPS is integrated behind the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know since I link up you? No, I guess that is it.
Its then 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 every upshot in insufficient fuel subconscious delivered to the engine. Might as well as be worth cleaning out the idle speed run motor / valve as these get clogged going on bearing in mind carbon and some brake cleaner washed through helps forgive things off.
I don’t have any check engine lights unless I unplug the MAF sensor. with the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping solid coming at idle.
