I have a 2004 ES330 when a hestitation problem. It is fine from a full end but like I go in relation to turns upon onto highway ramps, similar to 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 subsequent to the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face 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 fittingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. gone I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant with reference to 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I put up with the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know back I border you? No, I guess that is it.
I started the car going on this morning, it starts stirring and runs at 1750 and within a minute or fittingly climbs beyond 2500.. It is direction serene though, just habit well ahead than it should be. I along with checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it incite to exactly where it was. No vacuum leak sounds and all contacts verified. I environment fine about 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. bearing in mind the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is furthermore an intermittent popping unassailable coming at idle.
