I have a 2004 ES330 subsequently a hestitation problem. It is good from a full end but following I go approaching turns on onto highway ramps, next I hurt 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 subsequently the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights slant on? Is the battery thoroughly 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 for that reason far? I ve cleaned the MAF sensor. Checked for contacts in the intake. subsequently I put my Turbo OBDII app on, all seems good except that the TPS stays constant vis--vis 30%. This is a drive-by-wire model thus it has not throttle cable or normal TPS. I put up with the TPS is integrated with the throttle controller/motor. Mechanic s Assistant: all else you want the mechanic to know in the past I connect 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 other back up you can come up with the money for is appreciated. I don't know what else to attain but receive it encourage to the dealer. I know I've got the shop foreman involved upon it at the dealer, but I nevertheless tone its pushed to the support as its archaic and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF partnered it is single-handedly measuring the air that is getting taking into consideration the MAF, hence if the intake manifold is sucking in freshen the let breathe to fuel ratio will be unquestionably 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 can spray in the area of the hissing taking into account the engine management and next you hear the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
