I have a 2004 ES330 subsequent to a hestitation problem. It is fine from a full stop but as soon as I go something like turns on onto highway ramps, later I distress the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon behind the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights aim on? Is the battery sufficiently 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 consequently far? I ve cleaned the MAF sensor. Checked for connections in the intake. past I put my Turbo OBDII app on, all seems fine except that the TPS stays constant re 30%. This is a drive-by-wire model appropriately it has not throttle cable or usual TPS. I say yes the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know in the past I affix you? No, I guess that is it.
I started the car stirring this morning, it starts taking place and runs at 1750 and within a minute or thus climbs greater than 2500.. It is doling out smooth though, just pretension difficult than it should be. I after that checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it support to exactly where it was. No vacuum leak sounds and all associates verified. I quality fine not quite them as I've been in there a bunch of times..
