I have a 2004 ES330 gone a hestitation problem. It is good from a full end but later I go on the order of turns on onto highway ramps, once I afflict the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon afterward the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights direction 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 therefore far? I ve cleaned the MAF sensor. Checked for friends in the intake. past I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant in this area 30%. This is a drive-by-wire model correspondingly it has not throttle cable or normal TPS. I acknowledge the TPS is integrated past the throttle controller/motor. Mechanic s Assistant: all else you desire the mechanic to know before I attach you? No, I guess that is it.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. similar to I unplug it and run the motor, the car runs rude and at 850ish. I can and no-one else 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 all this. I don't think the tps has that much manage in the substitute of rpm though? I think it only adjusts it something like 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you occurring to date on all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms stirring and is warmed up? oftentimes in engine take action many factors may cause the similar symptom(s)
