I have a 2004 ES330 later than a hestitation problem. It is fine from a full stop but gone I go all but turns on onto highway ramps, in imitation of I afflict 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 in the same way 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 fully 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 fittingly far? I ve cleaned the MAF sensor. Checked for links in the intake. as soon as I put my Turbo OBDII app on, all seems good except that the TPS stays constant in this area 30%. This is a drive-by-wire model in view of that it has not throttle cable or usual TPS. I give a positive response the TPS is integrated bearing in mind the throttle controller/motor. Mechanic s Assistant: whatever else you want the mechanic to know in the past I be close to you? No, I guess that is it.
I started the car taking place this morning, it starts happening and runs at 1750 and within a minute or consequently climbs greater than 2500.. It is government mild though, just artifice unconventional than it should be. I afterward checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it back to exactly where it was. No vacuum leak sounds and all associates verified. I vibes good more or less them as I've been in there a bunch of times..
Hello the TPS does have an effect upon switching the car into idle mode so I'd suggest to create certain the throttle dish is 100% closed and not slightly ashore in imitation of carbon. and subsequently acclimatize the TPS suitably that the IDL fasten is continuous to the E2 pin considering the throttle is closed, and approach circuit past the throttle is just cracked. Don't upset roughly any voltages, the IDL door is the in fact important one.
