Chevy 4 3 Wiring Harness

I have a 2004 ES330 subsequent to a hestitation problem. It is fine from a full stop but like I go approximately turns on onto highway ramps, following I upset 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 than the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights turn on? Is the battery fully charged? With or without headlights on. Relatively new 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 correspondingly far? I ve cleaned the MAF sensor. Checked for associates in the intake. past I put my Turbo OBDII app on, anything seems good except that the TPS stays constant a propos 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I tolerate the TPS is integrated considering the throttle controller/motor. Mechanic s Assistant: everything else you want the mechanic to know in the past I attach you? No, I guess that is it.

Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me say you a little more just about the difficulty history. It currently has a master tech recognized idle ventilate direct valve and tps installed. without distressing anything, the last (used) ecu and my original, would run in the car without this symptom.

I don't have any check engine lights unless I unplug the MAF sensor. in the same way as the MAF is plugged in next the car will stall unless I put my foot on the accelerator. There is next an intermittent popping unquestionable coming at idle.
