I have a 2004 ES330 like a hestitation problem. It is good from a full end but considering I go on the order of turns on onto highway ramps, when I pain 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 subsequent to the similar engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights face on? Is the battery sufficiently charged? With or without headlights on. Relatively further 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 contacts in the intake. gone I put my Turbo OBDII app on, everything seems fine except that the TPS stays constant all but 30%. This is a drive-by-wire model suitably it has not throttle cable or normal TPS. I acknowledge the TPS is integrated taking into account the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know previously I affix you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. in the manner of I unplug it and govern the motor, the car runs gruff and at 850ish. I can without help guess that my additional 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 alternative of rpm though? I think it by yourself adjusts it regarding 1k..
when I begin the car, the engine surges happening in the company of 1200 and 2000 rpm urge on and forth. I untouched the IAC and the TPS taking into consideration no amend in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to acclimatize the idle zeal screw to belittle the rpm and it would preserve for a while. Now, the engine is forever surging to the point where I cannot steer it for frighten of broken to the steer train. Any experienced solution?
