I have a 2004 ES330 later than a hestitation problem. It is fine from a full stop but subsequent to I go going on for turns upon onto highway ramps, taking into account 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 similar to the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face 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 links in the intake. when I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I consent the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know back I link up you? No, I guess that is it.
I started the car stirring this morning, it starts stirring and runs at 1750 and within a minute or appropriately climbs on top of 2500.. It is doling out serene though, just mannerism forward-looking than it should be. I in addition to checked the throttle screw plate/return screw, with intent turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and all contacts verified. I vibes fine more or less 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. taking into consideration the MAF is plugged in later the car will stall unless I put my foot on the accelerator. There is also an intermittent popping solid coming at idle.
