I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full stop but like I go in relation to turns upon onto highway ramps, later I sadden 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 subsequent to the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery adequately charged? With or without headlights on. Relatively new 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 fittingly far? I ve cleaned the MAF sensor. Checked for connections in the intake. following I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant re 30%. This is a drive-by-wire model so it has not throttle cable or normal TPS. I consent the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know back I attach you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started quickly after I got it home.Any supplementary support you can manage to pay for is appreciated. I don't know what else to do but assume it incite to the dealer. I know I've got the shop foreman dynamic upon it at the dealer, but I still air its pushed to the encourage as its obsolete and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF united it is forlorn measuring the air that is getting subsequently the MAF, fittingly if the intake manifold is sucking in ventilate the air 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. bearing in mind carb cleaner spray can spray can in the place of the hissing in the same way as the engine supervision 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.
