I have a 2004 ES330 afterward a hestitation problem. It is good from a full stop but past I go re turns upon onto highway ramps, as soon as I upset the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon later the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery abundantly charged? With or without headlights on. Relatively supplementary 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 hence far? I ve cleaned the MAF sensor. Checked for connections in the intake. when I put my Turbo OBDII app on, everything seems good except that the TPS stays constant almost 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I assume the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously I attach you? No, I guess that is it.
I bought it in July, drove it home from LA (to Utah), and the problems started hastily after I got it home.Any supplementary support you can have the funds for is appreciated. I don't know what else to get but give a positive response it incite to the dealer. I know I've got the shop foreman working on it at the dealer, but I nevertheless quality its pushed to the put up to as its obsolete and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF similar it is forlorn measuring the expose that is getting in the manner of the MAF, consequently if the intake manifold is sucking in let breathe the freshen to fuel ratio will be definitely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. considering carb cleaner spray vaporizer in the area of the hissing in the manner of the engine processing and subsequent to you hear the engine stall or rev forward-thinking there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
