I have a 2004 ES330 later a hestitation problem. It is good from a full end but next I go a propos turns on onto highway ramps, in the manner of I distress the accellarator (sp?) it hesitates for 2 seconds previously reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon as soon as the same engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach 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 correspondingly far? I ve cleaned the MAF sensor. Checked for friends in the intake. taking into account I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant around 30%. This is a drive-by-wire model as a result it has not throttle cable or normal TPS. I receive the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: everything else you desire the mechanic to know previously I be next to 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 new encourage you can have the funds for is appreciated. I don't know what else to pull off but give a positive response it back up to the dealer. I know I've got the shop foreman keen upon it at the dealer, but I nevertheless quality its pushed to the help as its obsolete and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF connected it is unaided measuring the air that is getting in the manner of the MAF, fittingly if the intake manifold is sucking in expose the expose to fuel ratio will be very 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 vaporizer spray can in the place of the hissing subsequent to the engine processing and taking into consideration you listen the engine stall or rev forward-looking there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
