I have a 2004 ES330 in the same way as a hestitation problem. It is good from a full stop but next I go all but turns upon onto highway ramps, subsequent to I hurt 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 bearing in mind the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights incline on? Is the battery abundantly charged? With or without headlights on. Relatively supplementary 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 associates in the intake. later I put my Turbo OBDII app on, whatever seems good except that the TPS stays constant approaching 30%. This is a drive-by-wire model as a result it has not throttle cable or usual TPS. I understand the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: whatever else you desire the mechanic to know before I affix you? No, I guess that is it.
I started the car stirring this morning, it starts going on and runs at 1750 and within a minute or hence climbs higher than 2500.. It is doling out mild though, just pretension vanguard than it should be. I after that checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it put up to to exactly where it was. No vacuum leak sounds and all links verified. I feel fine just about 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 consequently I'd suggest to make certain the throttle dish is 100% closed and not slightly beached with carbon. and subsequently accustom yourself the TPS suitably that the IDL fix is continuous to the E2 pin taking into account the throttle is closed, and retrieve circuit past the throttle is just cracked. Don't distress practically any voltages, the IDL open is the in fact important one.
