I have a 2004 ES330 subsequent to a hestitation problem. It is good from a full end but next I go vis--vis turns on onto highway ramps, once I afflict 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 the similar engine and it jumps off the start and has no hesitation. Mechanic s Assistant: Will the headlights approach on? Is the battery adequately charged? With or without headlights on. Relatively supplementary battery.

Checked for associates in the intake. considering I put my Turbo OBDII app on, anything seems fine except that the TPS stays constant something like 30%. This is a drive-by-wire model in view of that it has not throttle cable or normal TPS. I bow to the TPS is integrated next the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know before I be next to you? No, I guess that is it.

I can without help guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much direct in the every second of rpm though? I think it unaccompanied adjusts it on the order of 1k..
I'm reviewing your ask now, and will reveal incite as soon as your answer ASAP. Rgds Greg. What deformity codes do you have. Does the engine govern afterward the MAF disconnected. afterward the noisy hissing hermetically sealed this could be your problem. This could be a large vacuum leak ,with the MAF united it is abandoned measuring the let breathe that is getting next the MAF, appropriately if the intake manifold is sucking in expose the expose to fuel ratio will be no question out and cause the engine to stal
