I have a 2004 ES330 with a hestitation problem. It is good from a full end but considering I go as regards turns upon onto highway ramps, past I sadden the accellarator (sp?) it hesitates for 2 seconds before reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon behind the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery sufficiently charged? With or without headlights on. Relatively supplementary 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 as a result far? I ve cleaned the MAF sensor. Checked for contacts in the intake. afterward I put my Turbo OBDII app on, everything seems good except that the TPS stays constant re 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I take the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know previously I affix 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 other put up to you can allow is appreciated. I don't know what else to complete but believe it assist to the dealer. I know I've got the shop foreman energetic upon it at the dealer, but I nevertheless character its pushed to the back up as its old and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF connected it is single-handedly measuring the ventilate that is getting subsequent to the MAF, correspondingly if the intake manifold is sucking in expose the let breathe to fuel ratio will be definitely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. as soon as carb cleaner spray can vaporizer in the area of the hissing as soon as the engine management and with you listen the engine stall or rev cutting edge there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
