I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full stop but in the same way as I go not far off from turns on onto highway ramps, later I depress 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 as soon as the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint 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 therefore far? I ve cleaned the MAF sensor. Checked for associates in the intake. once I put my Turbo OBDII app on, all seems fine except that the TPS stays constant roughly 30%. This is a drive-by-wire model appropriately it has not throttle cable or normal TPS. I allow the TPS is integrated afterward the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know in the past I be next to you? No, I guess that is it.
I bought it in July, drove it house from LA (to Utah), and the problems started immediately after I got it home.Any supplementary back you can offer is appreciated. I don't know what else to reach but endure it help to the dealer. I know I've got the shop foreman enthusiastic upon it at the dealer, but I yet vibes its pushed to the support as its obsolescent and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF amalgamated it is forlorn measuring the freshen that is getting once the MAF, appropriately if the intake manifold is sucking in freshen 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 spray vaporizer in the area of the hissing like the engine management and later you hear the engine stall or rev unconventional there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
