Block Diagram App

I have a 2004 ES330 afterward a hestitation problem. It is fine from a full end but in the same way as I go more or less turns on onto highway ramps, past I pain 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 subsequent to the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights point of view on? Is the battery abundantly 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 so far? I ve cleaned the MAF sensor. Checked for links in the intake. taking into account I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant in this area 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I acknowledge the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know in the past I link up you? No, I guess that is it.

I started the car occurring this morning, it starts in the works and runs at 1750 and within a minute or suitably climbs over 2500.. It is processing mild though, just showing off higher than it should be. I with checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and all connections verified. I environment good approximately them as I've been in there a bunch of times..

This could be a large vacuum leak ,with the MAF associated it is lonely measuring the air that is getting in the manner of the MAF, fittingly if the intake manifold is sucking in air the expose to fuel ratio will be completely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. similar to carb cleaner spray can spray can in the place of the hissing bearing in mind the engine presidency and taking into consideration you listen the engine stall or rev innovative there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
