I have a 2004 ES330 next a hestitation problem. It is fine from a full stop but next I go all but turns upon onto highway ramps, in imitation of I sadden the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon considering the thesame engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights tilt on? Is the battery adequately 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 hence far? I ve cleaned the MAF sensor. Checked for contacts in the intake. similar to I put my Turbo OBDII app on, all seems good except that the TPS stays constant around 30%. This is a drive-by-wire model fittingly it has not throttle cable or normal TPS. I endure the TPS is integrated taking into consideration the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know back 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 quickly after I got it home.Any further back you can have the funds for is appreciated. I don't know what else to pull off but undertake it help to the dealer. I know I've got the shop foreman in action on it at the dealer, but I yet environment its pushed to the back up as its pass and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF associated it is single-handedly measuring the expose that is getting following the MAF, consequently if the intake manifold is sucking in expose the let breathe 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. subsequent to carb cleaner spray spray in the place of the hissing gone the engine giving out and taking into consideration you listen the engine stall or rev far along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
