I have a 2004 ES330 in imitation of a hestitation problem. It is fine from a full end but behind I go going on for turns upon onto highway ramps, in the manner of I sadden 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 later the thesame engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery adequately charged? With or without headlights on. Relatively other 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 friends in the intake. behind I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant in the region of 30%. This is a drive-by-wire model hence it has not throttle cable or normal TPS. I bow to the TPS is integrated in imitation of the throttle controller/motor. Mechanic s Assistant: anything else you desire the mechanic to know since I attach you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. taking into consideration I unplug it and manage the motor, the car runs severe and at 850ish. I can lonely guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much manage in the substitute of rpm though? I think it isolated adjusts it going on for 1k..
This could be a large vacuum leak ,with the MAF combined it is only measuring the let breathe that is getting similar to the MAF, thus if the intake manifold is sucking in let breathe the air to fuel ratio will be unconditionally out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. with carb cleaner vaporizer vaporizer in the place of the hissing following the engine supervision and once you hear the engine stall or rev far along there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
