I have Maxima SE 2000 automatic.Around 2500-3000 rpm my car has hesitation and bogs.I changed throtle position sensor,idle air control and repair air intake on the throtle body.Now is the interesting part.When the engine is cold everything is o.k.,but when he reach to optimal temperature begin hesitation and bugs around 2500-3000 rpm.I put the neutral gear and turn off the engine,switch on,put on the direct gear and... everything is o.k.The car run and accelerate perfect,don't has a problem,it's absolutely different car.I can't understand what is this?What suppose to do?I hope to somebody help me with information.Do you know guys for other case like mine?

 

The code is P0403.I must to reprogram the ECU or i must to do something else.Please help me.
