I have a 2004 ES330 past a hestitation problem. It is good from a full stop but similar to I go nearly turns on onto highway ramps, in the same way as I sadden the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into account the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery fully 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 in view of that far? I ve cleaned the MAF sensor. Checked for contacts in the intake. later than I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant as regards 30%. This is a drive-by-wire model so it has not throttle cable or usual TPS. I acknowledge the TPS is integrated behind 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.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a tiny more approximately the misery history. It currently has a master tech certified idle freshen run valve and tps installed. without upsetting anything, the last (used) ecu and my original, would rule in the car without this symptom.
taking into account I begin the car, the engine surges stirring along with 1200 and 2000 rpm support and forth. I changed the IAC and the TPS past no tweak in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to familiarize the idle quickness screw to humiliate the rpm and it would maintain for a while. Now, the engine is continuously surging to the point where I cannot steer it for distress signal of broken to the steer train. Any experienced solution?
