I have a 2004 ES330 later a hestitation problem. It is fine from a full stop but afterward I go around turns on onto highway ramps, following I upset the accellarator (sp?) it hesitates for 2 seconds in the past 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 incline on? Is the battery adequately 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 appropriately far? I ve cleaned the MAF sensor. Checked for contacts in the intake. gone I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant in the region of 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I take the TPS is integrated similar to the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I affix you? No, I guess that is it.
I started the car occurring this morning, it starts occurring and runs at 1750 and within a minute or thus climbs higher than 2500.. It is management smooth though, just exaggeration unconventional than it should be. I afterward checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it back to exactly where it was. No vacuum leak sounds and every contacts verified. I tone fine roughly 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. subsequently the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping hermetic coming at idle.
