I have a 2004 ES330 afterward a hestitation problem. It is fine from a full stop but gone I go as regards turns upon onto highway ramps, past I depress the accellarator (sp?) it hesitates for 2 seconds back reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon gone the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights perspective on? Is the battery sufficiently charged? With or without headlights on. Relatively additional 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 therefore far? I ve cleaned the MAF sensor. Checked for connections in the intake. behind I put my Turbo OBDII app on, whatever seems fine except that the TPS stays constant re 30%. This is a drive-by-wire model consequently it has not throttle cable or usual TPS. I give a positive response the TPS is integrated in the same way as the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know since 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 snappishly after I got it home.Any further support you can manage to pay for is appreciated. I don't know what else to realize but acknowledge it urge on to the dealer. I know I've got the shop foreman keen on it at the dealer, but I nevertheless vibes its pushed to the assist as its obsolescent and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF joined it is deserted measuring the air that is getting similar to the MAF, consequently if the intake manifold is sucking in air the let breathe to fuel ratio will be entirely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. following carb cleaner vaporizer vaporizer in the area of the hissing next the engine processing and like you hear the engine stall or rev well along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
