I have a 2004 ES330 later than a hestitation problem. It is good from a full stop but afterward I go just about turns on onto highway ramps, following I sadden the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon subsequent to the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights point on? Is the battery abundantly 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 in view of that far? I ve cleaned the MAF sensor. Checked for connections in the intake. later than I put my Turbo OBDII app on, everything seems good except that the TPS stays constant approaching 30%. This is a drive-by-wire model thus it has not throttle cable or usual TPS. I assume the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know previously I affix 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 under the weather pump will every upshot in insufficient fuel being delivered to the engine. Might with be worth cleaning out the idle readiness rule motor / valve as these get clogged stirring subsequent to carbon and some brake cleaner washed through helps pardon things off.
I don't have any check engine lights unless I unplug the MAF sensor. in the same way as the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is plus an intermittent popping hermetically sealed coming at idle.
