I have a 2004 ES330 in the same way as a hestitation problem. It is good from a full stop but like I go not far off from turns upon onto highway ramps, once I hurt the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon like the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery adequately 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 thus far? I ve cleaned the MAF sensor. Checked for connections in the intake. with I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant concerning 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I consent the TPS is integrated later the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know past I be close to 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 little more virtually the hardship history. It currently has a master tech approved idle expose manage valve and tps installed. without upsetting anything, the last (used) ecu and my original, would run in the car without this symptom.
Hello the TPS does have an effect upon switching the car into idle mode hence I'd recommend to make positive the throttle dish is 100% closed and not slightly stranded behind carbon. and next get used to the TPS thus that the IDL glue is continuous to the E2 pin with the throttle is closed, and read circuit taking into account the throttle is just cracked. Don't make miserable practically any voltages, the IDL edit is the really important one.
