after you MAP whack/ ECU reset make sure your battery is in top shape. while in storage is something might be draining the battery? alarm or something... mine fluttered like that when my battery started to die...

maybe your being punished for not driving...

 

i'd have to agree with the TPS. i went through the same thing as well. I also went through the same thing when i had my gsr. thing about them rev happy honda engines is that everyone looooooves to take them as high as possible. my dad helped me take a look at my gsr. unplugged the tps and plugged it right in. i had a friend do the same with my '03 s2k and saaame result. she now purs juuust the way i want her to. according to my mechanic guy it was probably the folks that installed my aem ems and they must've "done something" when they tuned my car.

 

oh yeah, i first took my s2k to honda and they tried to get me to buy a new throttle body. yes, it's the "only" way to buy a new tps. but it helps to at least try to mess around with the tps first.
