I've read a ton of threads on Runners hesitating, but can't find exactly what mine does.

When I'm driving it runs fine, but when I "stomp" on it to pass or something I can feel a very slight hesitation/ sputter. I noticed it more the other day when it rained. When I accelerated normal it hesitated and sputtered pretty bad. After a bit of driving it seemed to go away. Then yesterday I ran it through a carwash and while accelerating to drive out of it, it did it again (ran fine until the wash). Today it rained all night and when I started it to go to work, it started then promptly stalled out. It did this 3 times until I held on the accelerator while starting and rev'd it to keep it running. Then after a few it seemed to clear up only with the usual faint hesitation under hard acc.

Any ideas?

Stalling at idle: Time to clean the IAC(search),also clean the throttlebody and MAF while you are there..

sputter when wet:check for condensation at the spark plug tubs and where the wires snap onto the coils..and a general good inspection with a flashlight pay close attention to all your wire connectors,MAF,TPS,coild,injectors,cam/crank position,ect...
