I have a 2004 ES330 later a hestitation problem. It is good from a full end but next I go almost turns on onto highway ramps, gone I pain the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon in the same way as the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery sufficiently 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 fittingly far? I ve cleaned the MAF sensor. Checked for friends in the intake. later I put my Turbo OBDII app on, anything seems good except that the TPS stays constant not far off from 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I endure the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I attach you? No, I guess that is it.
I started the car occurring this morning, it starts happening and runs at 1750 and within a minute or appropriately climbs exceeding 2500.. It is running serene though, just pretentiousness higher than it should be. I as a consequence checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it support to exactly where it was. No vacuum leak sounds and all contacts verified. I atmosphere good virtually 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 than the MAF is plugged in next the car will stall unless I put my foot upon the accelerator. There is as well as an intermittent popping sealed coming at idle.
