I have a 2004 ES330 later a hestitation problem. It is fine from a full end but in imitation of I go regarding turns upon onto highway ramps, later than I sadden the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon taking into consideration the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery thoroughly charged? With or without headlights on. Relatively further 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 for that reason far? I ve cleaned the MAF sensor. Checked for contacts in the intake. subsequently I put my Turbo OBDII app on, anything seems good except that the TPS stays constant in relation to 30%. This is a drive-by-wire model for that reason it has not throttle cable or usual TPS. I take the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I border you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. similar to I unplug it and govern the motor, the car runs rough and at 850ish. I can only guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much govern in the oscillate of rpm though? I think it and no-one else adjusts it approximately 1k..
I don't have any check engine lights unless I unplug the MAF sensor. behind the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is afterward an intermittent popping hermetically sealed coming at idle.
