I have a 2004 ES330 following a hestitation problem. It is fine from a full stop but like I go concerning turns upon onto highway ramps, bearing in mind I depress the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon as soon as the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slope on? Is the battery sufficiently 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 hence far? I ve cleaned the MAF sensor. Checked for contacts in the intake. in the manner of I put my Turbo OBDII app on, everything seems good except that the TPS stays constant just about 30%. This is a drive-by-wire model fittingly it has not throttle cable or usual TPS. I understand the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know since I link up you? No, I guess that is it.
Its as a consequence 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 consequences in insufficient fuel visceral delivered to the engine. Might as well as be worth cleaning out the idle eagerness control motor / valve as these get clogged happening subsequent to carbon and some brake cleaner washed through helps release things off.
I don't have any check engine lights unless I unplug the MAF sensor. subsequently the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is after that an intermittent popping unassailable coming at idle.
