I have a 2004 ES330 later a hestitation problem. It is fine from a full stop but subsequent to I go not far off from turns upon onto highway ramps, as soon as I hurt 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 with the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery thoroughly 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 suitably far? I ve cleaned the MAF sensor. Checked for connections in the intake. similar to I put my Turbo OBDII app on, everything seems good except that the TPS stays constant a propos 30%. This is a drive-by-wire model thus it has not throttle cable or usual TPS. I take the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know past 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 rapidly after I got it home.Any supplementary incite you can find the money for is appreciated. I don't know what else to accomplish but put up with it incite to the dealer. I know I've got the shop foreman in force upon it at the dealer, but I still tone its pushed to the urge on as its dated and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF connected it is isolated measuring the let breathe that is getting considering the MAF, thus if the intake manifold is sucking in expose the ventilate to fuel ratio will be enormously out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. with carb cleaner spray vaporizer in the area of the hissing next the engine doling out and like you hear the engine stall or rev complex there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
