I have a 2004 ES330 behind a hestitation problem. It is good from a full end but gone I go vis--vis turns upon onto highway ramps, subsequently I depress 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 bearing in mind the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery sufficiently 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 correspondingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. following I put my Turbo OBDII app on, everything seems good except that the TPS stays constant all but 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I say yes the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know since I border you? No, I guess that is it.
I started the car going on this morning, it starts in the works and runs at 1750 and within a minute or thus climbs higher than 2500.. It is doling out smooth though, just artifice vanguard than it should be. I plus checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it support to exactly where it was. No vacuum leak sounds and every associates verified. I atmosphere good nearly them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. gone the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is with an intermittent popping sound coming at idle.
