I have a 2004 ES330 past a hestitation problem. It is good from a full stop but with I go approaching turns upon onto highway ramps, afterward I depress the accellarator (sp?) it hesitates for 2 seconds since reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon afterward the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights viewpoint on? Is the battery abundantly charged? With or without headlights on. Relatively additional 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 consequently far? I ve cleaned the MAF sensor. Checked for associates in the intake. taking into account I put my Turbo OBDII app on, anything seems good except that the TPS stays constant on the subject of 30%. This is a drive-by-wire model therefore it has not throttle cable or normal TPS. I take the TPS is integrated once the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know past 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 brusquely after I got it home.Any other assist you can provide is appreciated. I don't know what else to do but acknowledge it encourage to the dealer. I know I've got the shop foreman dynamic upon it at the dealer, but I nevertheless character its pushed to the assist as its outmoded and everyone loses in this situation.

If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later than carb cleaner vaporizer vaporizer in the place of the hissing afterward the engine direction and later you hear the engine stall or rev well ahead there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
