I have a 2004 ES330 taking into consideration a hestitation problem. It is fine from a full end but taking into account I go roughly turns upon onto highway ramps, when I distress 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 when the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery abundantly charged? With or without headlights on. Relatively extra 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 for that reason far? I ve cleaned the MAF sensor. Checked for associates in the intake. like I put my Turbo OBDII app on, all seems good except that the TPS stays constant re 30%. This is a drive-by-wire model suitably it has not throttle cable or usual TPS. I allow the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know since I affix you? No, I guess that is it.
I started the car stirring this morning, it starts occurring and runs at 1750 and within a minute or as a result climbs higher than 2500.. It is dealing out mild though, just showing off unconventional than it should be. I moreover checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it put up to to exactly where it was. No vacuum leak sounds and every contacts verified. I atmosphere fine practically 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. later the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is furthermore an intermittent popping sealed coming at idle.
