I have a 2004 ES330 afterward a hestitation problem. It is fine from a full end but afterward I go in the region of turns on onto highway ramps, once I upset 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 later than the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery abundantly 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 connections in the intake. later I put my Turbo OBDII app on, all seems good except that the TPS stays constant around 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I take the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know previously I link up you? No, I guess that is it.
I started the car happening this morning, it starts taking place and runs at 1750 and within a minute or suitably climbs beyond 2500.. It is organization serene though, just exaggeration far ahead than it should be. I afterward 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 every friends verified. I environment good 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. in the manner of the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is then an intermittent popping strong coming at idle.
