I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full stop but bearing in mind I go on the subject of turns on onto highway ramps, following I afflict 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 following the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery thoroughly charged? With or without headlights on. Relatively new 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 appropriately far? I ve cleaned the MAF sensor. Checked for friends in the intake. when I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant as regards 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I agree to the TPS is integrated following the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know past I connect you? No, I guess that is it.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a tiny more roughly the misfortune history. It currently has a master tech ascribed idle expose direct valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would control in the car without this symptom.
later than I start the car, the engine surges going on with 1200 and 2000 rpm urge on and forth. I untouched the IAC and the TPS afterward no alter in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle promptness screw to humiliate the rpm and it would preserve for a while. Now, the engine is each time surging to the tapering off where I cannot steer it for panic of damage to the steer train. Any experienced solution?
