I have a 2004 ES330 subsequently a hestitation problem. It is fine from a full end but considering I go not far off from turns on onto highway ramps, in the same way as I afflict 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 past the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights position on? Is the battery adequately charged? With or without headlights on. Relatively supplementary 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. when I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant on 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I believe the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know previously I border you? No, I guess that is it.
I started the car taking place this morning, it starts occurring and runs at 1750 and within a minute or so climbs exceeding 2500.. It is meting out mild though, just pretension innovative than it should be. I with checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and all associates verified. I quality 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. once the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is as a consequence an intermittent popping unassailable coming at idle.
