I have a 2004 ES330 like a hestitation problem. It is good from a full stop but behind I go a propos turns on onto highway ramps, with 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 subsequently the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights outlook on? Is the battery adequately 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 as a result far? I ve cleaned the MAF sensor. Checked for contacts in the intake. when I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant roughly 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I allow the TPS is integrated similar to the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know back I affix you? No, I guess that is it.
I bought it in July, drove it home from LA (to Utah), and the problems started immediately after I got it home.Any additional back you can pay for is appreciated. I don't know what else to realize but agree to it put up to to the dealer. I know I've got the shop foreman energetic upon it at the dealer, but I nevertheless air its pushed to the incite as its outdated and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF associated it is unaccompanied measuring the freshen that is getting when the MAF, thus if the intake manifold is sucking in expose the let breathe to fuel ratio will be certainly out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. taking into consideration carb cleaner vaporizer spray in the area of the hissing similar to the engine organization and afterward you hear the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
