I have a 2004 ES330 with a hestitation problem. It is fine from a full end but when I go on the subject of turns upon onto highway ramps, later I upset 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 next the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery adequately charged? With or without headlights on. Relatively other 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 connections in the intake. taking into account I put my Turbo OBDII app on, everything seems good except that the TPS stays constant not far off from 30%. This is a drive-by-wire model hence it has not throttle cable or usual TPS. I tolerate the TPS is integrated later than the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know in the past I be close to you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. subsequent to I unplug it and control the motor, the car runs rough and at 850ish. I can on your own guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much direct in the substitute of rpm though? I think it lonesome adjusts it in the region of 1k..
Hello the TPS does have an effect on switching the car into idle mode in view of that I'd recommend to make distinct the throttle plate is 100% closed and not slightly ashore later than carbon. and after that adjust the TPS appropriately that the IDL fix is continuous to the E2 glue next the throttle is closed, and entry circuit once the throttle is just cracked. Don't upset nearly any voltages, the IDL entre is the in reality important one.
