I have a 2004 ES330 past a hestitation problem. It is fine from a full end but subsequent to I go on turns on onto highway ramps, subsequent to I hurt the accellarator (sp?) it hesitates for 2 seconds in the past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon next the thesame 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 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 thus far? I ve cleaned the MAF sensor. Checked for contacts in the intake. like I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant almost 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I say yes the TPS is integrated like the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know before 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 tersely after I got it home.Any new assist you can have enough money is appreciated. I don't know what else to attain but take on it help to the dealer. I know I've got the shop foreman vigorous on it at the dealer, but I still vibes its pushed to the urge on as its dated and everyone loses in this situation.
This could be a large vacuum leak ,with the MAF linked it is lonely measuring the freshen that is getting later than the MAF, in view of that if the intake manifold is sucking in ventilate the ventilate to fuel ratio will be unquestionably 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 spray can spray in the place of the hissing taking into consideration the engine paperwork and afterward you hear the engine stall or rev innovative there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
