Gm Fuse Box Terminals

I have a 2004 ES330 in the manner of a hestitation problem. It is fine from a full stop but in imitation of I go nearly turns upon onto highway ramps, in imitation of I pain 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 in imitation of the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery fully charged? With or without headlights on. Relatively additional 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 correspondingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. in imitation of I put my Turbo OBDII app on, all seems fine except that the TPS stays constant roughly speaking 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I put up with the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know since I affix 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. with I unplug it and direct the motor, the car runs harsh and at 850ish. I can unaccompanied 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 all this. I don't think the tps has that much manage in the substitute of rpm though? I think it isolated adjusts it not far off from 1k..

This could be a large vacuum leak ,with the MAF combined it is forlorn measuring the ventilate that is getting once the MAF, appropriately if the intake manifold is sucking in air the let breathe to fuel ratio will be extremely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. behind carb cleaner vaporizer vaporizer in the place of the hissing subsequently the engine executive and past you listen the engine stall or rev far along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
