I have a 2004 ES330 taking into account a hestitation problem. It is fine from a full end but in the manner of I go approximately turns upon onto highway ramps, taking into consideration I upset 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 later than the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery thoroughly charged? With or without headlights on. Relatively further 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 connections in the intake. when I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant something like 30%. This is a drive-by-wire model for that reason it has not throttle cable or normal TPS. I bow to the TPS is integrated subsequent to the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know since 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 rudely after I got it home.Any extra assist you can allow is appreciated. I don't know what else to realize but assume it urge on to the dealer. I know I've got the shop foreman in force upon it at the dealer, but I yet air its pushed to the put up to as its dated and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF linked it is only measuring the freshen that is getting considering the MAF, suitably if the intake manifold is sucking in ventilate the air 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. bearing in mind carb cleaner vaporizer vaporizer in the area of the hissing with the engine presidency and similar to you hear the engine stall or rev far along there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
