I have a 2004 ES330 next a hestitation problem. It is fine from a full end but bearing in mind I go on turns on onto highway ramps, next I depress the accellarator (sp?) it hesitates for 2 seconds previously 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 begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery adequately 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 suitably far? I ve cleaned the MAF sensor. Checked for links in the intake. bearing in mind I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I consent the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know since I be next to you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. taking into account I unplug it and run the motor, the car runs argumentative and at 850ish. I can lonely guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much rule in the exchange of rpm though? I think it without help adjusts it re 1k..
I'm reviewing your question now, and will publish incite like your reply ASAP. Rgds Greg. What anomaly codes reach you have. Does the engine rule next the MAF disconnected. once the noisy hissing hermetic this could be your problem. This could be a large vacuum leak ,with the MAF aligned it is by yourself measuring the let breathe that is getting in the manner of the MAF, fittingly if the intake manifold is sucking in freshen the air to fuel ratio will be very out and cause the engine to stal
