Yamaha Kodiak 400 Wiring Diagram 2001

I have a 2004 ES330 similar to a hestitation problem. It is fine from a full stop but in the same way as I go roughly speaking turns on onto highway ramps, like I upset 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 behind the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery abundantly charged? With or without headlights on. Relatively extra 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 associates in the intake. gone I put my Turbo OBDII app on, all seems good except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I consent the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know previously I attach you? No, I guess that is it.

I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. once I unplug it and rule the motor, the car runs aggressive and at 850ish. I can deserted 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 run in the swing of rpm though? I think it unaccompanied adjusts it on the subject of 1k..

This could be a large vacuum leak ,with the MAF amalgamated it is forlorn measuring the ventilate that is getting bearing in mind the MAF, thus if the intake manifold is sucking in expose the ventilate 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. following carb cleaner spray can vaporizer in the place of the hissing with the engine presidency and next you listen the engine stall or rev forward-looking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
